i disagree that disagreeing is normal

The GC/PS2/XB gen was the one gen when I had all the systems, and the only time I've owned a Playstation system, and the PS2 was by far my least played system that gen, even though I got it second out of the three. So, easy pick, Switch by a light year.

Ps2 was a legendary console for sure. But to me, S1 has more replayable titles. I simply can’t see myself going back to replay ps2 games.

Sure, if you are playing what you want, you are where you should be.

You did transition to being a PC gamer recently tho, did you not? PC has a lot to offer.

It's not gonna turn into a console war but it might as well be asking for it 😅

Hum anyway on my opinion, it goes to say Imma gonna elect the Switch 1 for the title but I do think the arguments for each case are gonna be widely different for some. I'd argue the 7th Gen was basically the last real time in console gaming where there was the possibility for mid-size team devs and bigger teams alike to try out the freshest of ideas, new IPs and take wild turn with old IPs without suffering from devastating financial loses resulting in closures galore. Before the industry over-industrialized itself.

And the PS2 library shows it because it's just overall fullest catalog in terms of spectrum you could imagine.
As for the hardware, it advanced the the metrics of what could be possible for home console but it wasn't really on the cutting edge of its peers.
Same could be said about the Switch really, wasn't a cutting edge console if it's generation, though it actually a massive step for handheld gaming as a whole and it completely opened the possibility for high end portable gaming that would finally be seen on par with what is offered on home console. Therefore it is a win there.

As for the library, the Switch experienced the highest highs Nintendo and it's multitude of franchises could likely ever experience in their lifetime, surpassing records than the PS2 hasn't touched by far despite selling so many consoles.

Both library shares games with the most critically acclaims and genre defining titles of their generation or gaming history you could say.
So to determine which you'd prefer goes to one's own experience and taste.

I haven't played the PS2 enough during my childhood to get a grip for it sadly, so my choice stops at the Switch handily

Yeah I did. I’ve mostly been experimenting with emulation though. Haven’t played a single AAA yet— I’m waiting on discounts, plus many of the current AAA games I already own but on PS5 (and I’d rather just borrow my bro’s PS5 than pay for a second copy).

As far as sales go, PS2 sold more and had a far greater marketshare, so that's an easy win for Sony. As for library, it also had an objectively stronger third-party lineup, so I would give it the nod there too. Obviously for first-party games, it's hard to pick against Nintendo but that's subjective so, I'll leave that one alone.

Overall, I think the winner should be the PS2. I was a college-aged adult at the time, and for people my age, other than maybe a biased Nintendo fan, it would be incredibly difficult to justify arguing against the PS2 in this debate. The only dedicated console in history that can best its dominance (market-share; cross-over awareness;pop-culture identity etc.) was the NES. That's how huge it was. There was simply no other console that gen as far as the average consumer went. You either had a PS2 or you didn't have a game console. It was the alpha and omega. The true king.

Shame that you can't bring "both" option.
I love PS2. Switch gained some appreciation thanks to games exclusivity apart from the fact that this state is not on PlayStation or Xbox.
Today's Xbox Game Showcase could change that, and it promises to be a wonderful time for gaming at the end of this generation. Nintendo remains in top form.
As for the PS2, it's a timeless piece of hardware; there's only one king. It wouldn't be a bad thing if there was a second king – the Switch. There are few brilliant consoles, and these deserve this title without distinction.

PS2 was my least favorite Sony console, so yeah Switch.

I feel like all these console vs console wars are getting a bit overdone, this is like what, 5 of them in the last week and change?

As firebush said, it feels a bit like stirring the pot at this point.
