Sadly, my old rated consoles can't be changed overtime, here's copy/paste'ed.

Nintendo DS: 9/10: A new way gameplay with dual-screen handheld and 1st fully achieved Super Mario 64 from the 6th gen N64 on a handheld console.(2005)

PSP: 9/10 A PS2 games on a handheld console, nuff said!(2006)

Xbox 360: 8/10 Quality games and performance hardware are great, but lack of onboard Wi-Fi adapter and dated disc drive.(2009)

PS3: 5/10 Good exclusive games, but horrendous overpowered, overpriced, oversized box, heavy and poorly performance wise.(2007)

Nintendo Wii: 7/10 New gameplay with a motion controls, but poorly underpowered console.(2008)

Nintendo 3DS: 7/10 A better quality games, but lack of ZR/ZL buttons, 2nd circle-pad and overpriced(2011)

PSVita: 4/10 Dated games! Overpriced handheld console! Overpriced memory cards and especially undersized! Lack of L2/L3/R2/R3! GIMMICK!!!(2012)

Nintendo Wii U: 8/10 I love the Wii U gamepad, but still underpowered CPU/GPU speedwise and it's a shame that third party publishers don't care about the console.(2013)

PS4: 7/10 Ehhhh....(2014)

Xbox One: 6/10 TV. (2014)

New Nintendo 3DS: 9/10 Much better than the old N3DS, thanks Nintendo, but why 2nd circle-pad is so tiny!(2015)

PS4 Pro: 8/10 A nice upgrade from OG PS4, you get 4K resolution and high framerate at 1080p, sadly it requires patch for the games depending on publishers. Oh, and lack of external HDD support, what a bummer!(2016)

Xbox One S: 8/10 Improved performance and supported 4K disc drive, but still...(2016)

Switch: 10/10 I'm addicted.(2017)

Well, that's about it, forgive me for whining or insulting on PS3, Vita and PS4 as well as PS4 Pro i know it got boost mode months ago.

PSP- 10/10
DS- 8/10
Xbox 360- 9.5/10
Wii- 8/10
PS3- 7/10
3DS- 8/10
Wii U- 7/10
Xbox One- 7.5/10

SONY

• PS4 Pro (9/10): By far my most used and appreciated system. Games look great on my 4K, even if people want to argue about it being upscaling. It'd get a higher score of it was backwards compatible and had a 4K Blu-ray Drive.
• PS4 (8/10): The predecessor to my Pro, my PS4 got just as much use daily as my Pro does prior to it's replacement. Like the Pro, it would get higher marks if I could play my PS3 games on it.
• PS3 60GB (8/10): My backwards compatible PS3 got a fair amount of use as well when I still used it, and it had just about everything I could have wanted in a platform... Except crossgame chat.
• PS2 Slim (8.5/10): Dat library. Limited online support in an era of budding online services and a particularly nasty failure rate are what limits this score from hitting a 9/10.
• PS1 (6.5/10): Surprise; when the PS1 came out, I was a die-hard Sega can and was vehemently against it. I did eventually warm up to it, though, enjoying several Final Fantasy titles on it, as well as Soul Reaver. But my initial distaste for it will always remain.
• PSP (8/10): Monster Hunter Freedom. Birth By Sleep. Crisis Core. Most of my favorite games for a period of my life were on this system. It's a shame its limited online capabilities ruined a perfect score from me.
• Vita (7/10): I loved the Vita out of the gate, and will still grab it over my 3DS... But my inability to play Crisis Core or Birth By Sleep on it severely hamper my enjoyment of it.

Yeah, that. You wanna hear the truth? Compatibilty was lackluster at launch like crazy, but the good news is it got many supports(except backward PS1/PS2/PS3 disc based) nowadays. So again, i can't change old rated consoles.

Only current and last gen stuff based off my experience.

360: 8/10
PS4: 9/10
Wii: 8/10
Wii U: 4/10

DS: 9/10
3DS: 8/10
PSVita: 7/10

No strong opinion of Switch as of now.

Hehe i know BraLoD my old opinion was harsh, if only LoD was on the PS4, i wouldn't care about compatibilty and straight up to 9/10

Yeah, I played some of them, but never owned a console. 

Since 0eople rated their consoled post 7th gen ilk do that also.

N64- 7.5/10

Gamecube- 7.5/10

GBA- 7/10

Dreamcast- 8/10

Xbxo- 8.5/10

PS2- 8/10

Well, I guess I'll do every console I have while I'm at it. Now, this is a narrow scale, meaning that the full points will be used, and the numbers have to be taken into account with the context. I'll do out of 5 stars too, because I attempted the 10 point scale and it was too hard.

5* - PS1, PS2
4* - N64, GC, PS3
3* - Wii, XB, DC
2* - SAT, SNES, GEN, PS4, WiiU
1* - NES, SMS
0* - INT

Now, I like all of my consoles, so 0* does not mean that it's horrible.

PS3: 7/10 (Awesome library with some great exclusives...slow start and high launch price hold it back)

360: 8/10 (Not my console of choice, but it revolutionized online play for consoles. Exclusives died out early though and RRoD hold it back from a perfect score)

Wii: 6.5/10 (Had a lot of fun games. Skyward Sword is an example of motion controls done right and one of the games that showed its true potential. However much of it's library was shovelware despite having many gems of its own.)

PS4: 9/10 (Best 3rd party games and exclusive library when compared to the X1. If it had BC like X1 with PS3 games, it would be a 10)

X1: 5/10 (lesser version of the PS4 with a few lack luster exclusives. The BC is nice, but not enough to make up for its shortcomings. It does the job though).

WiiU: 6.5/10 (Great side console to go with the PS4. A good amount of quality exclusives and better than the X1, but lacks the library required to be a primary console. Can play game of the generation)

Vita: 6/10 (Same situation as the WiiU, but has excellent Japanese support. Niche handheld with wasted potential)

3DS 10/10 (Has a huge library and is BC with DS games. Coming up on the end of its life, it had a great run)

Switch 10/10 (At least so far. The current games line up is very promising and already has the best version of the GotG. Being able to take current gen AAA experiences on the go wins it a perfect score, so long as the games keep coming to back it up. While weaker in power than the current gen consoles, it is a beast of a handheld. In terms of actual use, I see this being my primary device moving forward due to the ability to seemlessly switch between my TV and handheld mode.)
