Tried some vegan "feta" type cheese for my salad, based on cocos oil, and it was pretty bad. It had a terrible stink and taste like overripe cheese, which is kinda the opposite of what you'd expect from this type. It also became incredibly smeary immediately when I tried to crumble it, so it only mimics the original consistency when it is untouched.
The only vegan products that I've tried and liked so far were oat milk, which is pretty much tasting like regular milk at this point (at least my brand), some vegan Schnitzel which tastes not quite but close enough like those premade regular ones you'd get at a grocery store, and some "cut chicken" type stuff which honestly was pretty great in taste and consistency and definitely something I get again if I want to throw some mixed veggie bag into the pan. Everything else I've tried ranged from "meh" to "eugh". But I'm sure it's just a matter of more R&D.
