Depending on what games you play it’s anywhere from unusable (games with incompatible anticheat) to flat out better than windows even ignoring all the surrounding bullshit. But many of these gsmes with anticheat are among the most popular games in the world, so there’s plenty of reason not to change just bc of those for a lot of people.
Solely going off their burger patties (haven’t tried other stuff) I wouldn’t call beyond realistic, though it is very tasty (imo moreso than actual beef). It definitely doesn’t taste the same though.
I think there’s also a cultural issue, some people at least here in germany still consider it weird if you order the vegan/vegetarian version of anything, especially if you aren’t entirely vegan yourself. If that sort of pressure exists it’s also less likely for anyone to try plant based alternatives, no matter how good.
