Ooh fun.. Here's about where I'd place them. Left the PS3 and PS4 out as I've rarely played them. Never in fact owned a PS1 or PS2 either though I've played them (& watched friends play them) quite a bit more so I think that warrants inclusion. 
S: SNES was just the peak of gaming for me, the golden age. Love just about everything about the 16-bit era (other than the lack of online/4 player multi). Love the charming sprites, fast-paced gameplay that was usually tough but accessible. Platformers, APRGs, action titles, all great in this era. And for my money the SNES was the best of this era. Not to mention is home to some of my all-time favorite games to this day.
360's library was sick, in terms of quality, quantity, and diversity of titles (other than maybe the JRPG front). Allowed you to experience tons of epic games at a price that didn't break the bank. Solid online gameplay. And still owned most of the content yourself, and largely tied to the hardware, unlike the XBOne. Perfect sweet spot between modern and retro gaming. RROD taints its name a bit but I only ever had one issue (w/the drive) which was promptly fixed for free. And still have yet to have an issue with the updated model, which I've had since 2008.
A: Dreamcast is perhaps the most underrated console ever. Love the arcade-style games. Again, nice mix of titles from the cute and colorful to more epic, gritty. VMU was a cool, unique concept at the time. Just held back by the lack of support, and controller was a bit gigantic..
N64 is fantastic for 4-player multi, but lacking a bit on game quantity and single player games, controller is obviously funky. NES of course is classic, with probably a top 5 all-time game in Super Mario 3. Still, 8-bit is just a tad archaic feeling to me, and being 34 - just a tad before my time. Do have fond memories of playing it with my sister, cousin, & friends at the end of its lifecycle though. Love the versatility of Switch with its handheld-to-TV functionality. Overall library is great (esp with ports and indies), though could do with a bit more on the new game front from Nintendo. Get the occasional joy-con drift which bugs the crap outta me.
B: GameCube and Wii I have mixed feelings about - both for very different reasons. But overall positive for both, great memories with both. Cube is the more "core" console - but maybe a bit too core. Has that niche vibe between its weird controller and more hardcore Nintendo games that doesn't have a wide appeal. Ironically the biggest names - Mario and Zelda - have sort of weak showings here. Though strong on the 2nd party (& N published) front. Games like Tales of Symphonia, Eternal Darkness, Super Monkey Ball. Best version of Smash, Metroid Prime rules, and RE is well-represented on console. But third party rather weak overall.
Although I didn't play a ton of PS2, it's my favorite Sony console. It has the most games I'd be interested in playing. Genesis is Genesis. Slightly edgier counterpart to SNES which, despite only really getting into retroactively, I ended up enjoying. Sonic, Streets of Rage, ToeJam and Earl.. nuff said there.
Like N64, Wii was terrific more in terms of a multiplayer/social console. The motion control, Wiimote thing - while didn't always work - felt revolutionary and was amusing under the right circumstances. Wii Sports felt like experiencing games for the first time again. Of course, hardware was pretty weak, as was third party support (disregarding cheap ports and shovelware).
C: Don't have much to say beyond these higher tiers. XB One I play a ton but it's become like 70% an Overwatch machine for me essentially. Not too keen on the heavy emphasis of updates and services required for the thing and games to function. Not quite as much that appeals to me compared to 360. Controller is pretty close to perfection though. PS has that sort of retro charm going for it but I was just never too into the cinema-style games which are more linear and cutscene heavy, and PS (and Sony in general) has quite a few of these. & those graphics just have not aged well.
D: Never got into the original Xbox. Never liked the giant, bulky design of the console and controller. Had very little that appealed to me (at least that I couldn't also enjoy in better form on my 2004 desktop, ie Morrowind).
F: I could really get into why I dislike the Wii U but that'd be a whole nother wall of text heh. Needless to say - the cumbersome interface, bulky, cheap-feeling "gamepad," lack of titles, etc. all didn't do it any favors.
