Yes. Really enjoying my PS5 and Switch 2.

Lol, **** no.  Dude none of that is true.  My old 4070 ran circles around the ps5.  

Christ a 5060ti will spank a base ps5.  A 5070 takes out the Pro.  Prices are $250 and $500 respectively.

Everything about your post is just wrong.  

If you have the money, sure.

The PS5 is your only way to play the current gen games and the best way to play PS4 games. I don't have a XB1 or Series but I imagine the same is true.

Where do you shop for pc parts?  The 5060ti is $430 after being $50 off for the 16GB, they have the 8GB for $370 after $10 off. Amazon is the same price for the 8BG, and the 16GB isn't on sale so $480.  Still way better than some of the more expensive game cards, but if you're going to go pc you may as well invest in a better one.

Oh, yeah, good shout.  I was thinking about the price of the 5060, not 5060 ti.  Honest mistake.

And I 100% agree.  I would spend the extra money and go at least 5070 at $500 to $550.

The 5070 will obliterate the base ps5 and easily best the Pro.  

I have no idea why Legit thinks a xx90 is required.  I have a 4090 and run almost everything at 120 fps at a higher resolution than the ps5 while also having higher settings.  

Hmmm.
Wii U to Switch? No. Switch went up in price. Just skip straight to Switch 2 at this point unless you're really strapped for cash and think Switch Lite offers enough value.
Xbox One to Xbox Series? No. Xbox has gotten quite ridiculous in price.
PS4 to PS5? Yes. Go for the standard PlayStation 5 or splurge on PS5 Pro if you've been saving up for a while.
I don't think the next generation is going to be much cheaper if cheaper at all and I don't see the current 9th generation systems decreasing in price.

If we’re talking Nintendo? Switch 2 is the way (since it’s only $50USD more than NSWOLED). Is we’re talking PS5? PS4 is signficantly more economical than PS5, so there is reason to consider recommending old gen. If the person wants to play modern gen games, then ofc PS5 is the way. If the person is simply looking to play some good games, then they can either save a few hundred in the short-term by purchasing PS4 alongside tons of old games for $20 each OR they can fully commit to PS5 and have double the library available.

(If we’re talking Xbox? Just purchase a PS5 or an XBOne. That system is unreasonably expensive for its value. Plus, it’ll likely become obsolete by the end of next year.)

Like all things in life... The answer to that question is... Depends.

Unless you only play in docked mode... And only if there is a must-have game, I would stick with the Switch OLED over the Switch 2, it's a better console.

With the Xbox One > Series X and Playstation 4 > Playstation 5.... That depends on the games you are playing.

In my games room I am still running the VCR model Xbox One, I opened up the console and replaced the internal mechanical HDD with a speedy Crucial SSD... And it's perfect for Minecraft, there would be minimal/zero benefit in replacing that console with an Xbox Series device... And that would apply to most eSports titles which had a respectful presentation and performance profile on Xbox One/Playstation 4.

In short, upgrade if you feel a need, rather than merely upgrading due to societal/peer pressures.

A lot of people think gens are about power and not what they are actually about: succession. So yes, there are people who think the Switch 1 is the same generation as the Wii-U lol

As others have stated the answer is - maybe? It really depends on what games you are playing. Do you mainly play Fortnite, Roblox, or other GaaS games that run fine on PS4 and Xbox One? The answer is now. Do you want to play the latest single-player games? The answer is yes. 

However, at this point I'd say just get a PC IF you want to play first-party games from both PlayStation and Xbox. Plus you can use whatever controller you prefer rather than being stuck with just a PS controller on PS5 or Xbox controller on Xbox Series. 

I've gone the PC route and play games either with Game Pass or buy them on Steam.
