Goes deeper than that. Some like me consider it to be the primary system for old school ports like old Shmups/Arcade games. Esp with a flip grip you can turn the Switch into TATE mode. Xbox is my primary Gears/Shooter console even if they come to PS5. PS5 I used for almost everything else. Everyone has their own priorities. From broad to specific. There is no one answer.

For me, I've played Switch a lot more in the past 8 years than any other system.  Sometimes I will play a game on PS4, but not that often.  I don't own a PS5 or X|S, and I have no definite plan to buy one in the future.

Switch really is where gaming is at right now, and soon Switch 2 will be the main console where gaming is at.  PS5 only gets a few games each year that are not also on PS4.  PS5 is kind of a pathetic platform (and X|S is even worse).  To me PS5 gamers look a lot like N64 gamers from back in the day.  The main gaming platform has shifted to a different company, but they haven't realized it yet.

I think there's historical data showing that Nintendo consoles in general are more commonly owned by PS and Xbox owners, as opposed the "opposite" console in that rivalry. I don't think this is indicative of Switch being a default secondary console as such, but rather a result of Nintendo having a very different library to the "twins". It makes much more sense, from a perspective of software breadth, to purchase a Switch to go along with a PS or Xbox, rather than a counterpart with very similar offerings and formats.

Obviously, the Switch is the primary system for a majority of gamers on the platform, I don't see how it could have sold as well as it has if this wasn't the case. If anything, with associated costs of consoles and gaming in general today, I wouldn't be at all surprised if the number of multi-console ownership has declined sharply over this generation.

the difference is... N64 had, in fact, lots of exclusive games PSX users always wanted (Mario 64, Star Fox 64, GoldenEye, Turok series (4 games), Ocarina of Time and Majora's, Mario Kart 64 and Diddy Kong Racing, Perfect Dark, Banjo Kazooie and sequel, Star Wars Rogue Squadron, Wave Race 64, Conker Bad Fur Day, Pokémon Stadiums, F-Zero X, Super Smash Bros., both F-1 WGP, ISS series (a different one from the PSX Winning Eleven based) and for sure, many others depending on the tastes, like Goemon 64, Castlevania 3D games, Star Wars Racer, Paper Mario, PilotWings 64, Ogree Battle 64, Body Harvest, Hybrid Heaven, Indiana Jones and the Infernal Machine, Mario Parties,...

Of course PSX already had exclusives like FFVII or MGS, but in the end, many PSX games had good or excellent exclusives alternatives in N64 (like WDC for GT, 1080 for the Cool Boarders series, or Mace, Fighter's Destiny or Flying Dragon instead of Tekkens).
And many other great games just appeared as multiplatform games, like Forsaken, Shadowman, Mortal Kombat 4, V-Rally, Tony Hawk series, or Rayman 2 (this last one, a year later in PSX). Also, that impossible port of RE2 for N64, with extras, plus analogue controls option for the first time in the series.

(Man, even that RE Zero ALMOST appeared for the N64 as an exclusive: They cancelled it and turned it a GC game far in its development. Like Nintendo did with Eternal Darkness. Both would have been HUGE releases in the last N64 days).

PSX basically totally defeated N64 only if you loved classic role playing games. PSX started to got a huge colossal quantity of them by late 1997. But until FFVII arrived in the western world, Saturn had a better RPG games catalogue than PSX, and that's (surprisingly for many) true.

PS5, instead, basically have almost none exclusives games Switch users really want: They have already almost everything.

It depends. There are people who don't have other consoles, so Switch would absolutely be their primary system. And there are those who might have a PlayStation or Xbox but really love Nintendo games and play some third-party games on Switch.
For those of us who play plenty of games, it's common to have Switch as a secondary system. PS4 was my primary system from 2019-2022, with PS5 as my primary from 2022-present. Switch was my primary from 2017-2019.

I remember with Ikaruga, there was a setting where you could flip the view and turn your actual TV sideways. Now that is hardcore.

Not really that different.  N64 had a small amount of exclusive games compared to other consoles of the 90's.  PS5 has a small amount of exclusive games by today's standards.  Some people really like those exclusives.  A person could say that Baldur's Gate 3 (for example) is worth the purchase of a PS5, just like people make the case for the various N64 games.  In the end the Switch has a lot more games available than the PS5, and the PS1 had a lot more games available than the N64.  A lot of the reason why people bought the N64/PS5 is that the SNES/PS4 were successful systems, respectively.  The gaming environment has changed and some people transition slower than others.

Definitely.
I would never just have a Switch and nothing else to play games.
Meanwhile PS or PC nowdays, yeah.

Is this a troll thread?

There's 50million Switch owners (probably closer to 100m when you account for crossover) who don't own a PS5 or XBwhatever tf.

Sounds like the HD twins are getting nervous about their inevitable disruption in the 10th gen.

That Switch 'click' we've all heard for most of the past decade was the videogame equivalent of Thanos in Marveland. Can't fight the inevitable.

Those "primary" systems couldn't even outsell Switch combined even though they had GTA, CoD and proper Fifa.

Game Over.
