It depends on what you're eating it with honestly. I don't think that most vegan cheeses are "good" either, but I find it easier for vegan cheeses to do their job with something like macaroni and cheese more than it is for them to do so with, say, a sandwich. Also, adding nutritional yeast really is the main game changer here. It adds an extra degree of more addictive "cheesy" flavor. It was most certainly very good for me either way.

There are good vegan deli slices and vegan cheese sauces, but no vegan cheeses that are so good on their own that you'd put them on a cheese board.

Also you can't melt the deli slices into cheese sauce, they're actually completely different things.

What folks have said is true but genwrallt speaking vegan cheese has advanced quite a bit. It's not around where I am, but I work at a pretty fancy pizza place and our chef goes to an annual international pizza contest held in Vegas and it kinda doubles as a trade show, it's absurd but there ya go. Anyway, there was a vegan cheese product being demo'd that was specifically made for a crazy hot brick an stone pizza oven that starts out as a liquid and turns into a cheesy texture as it heats up and is made of non sketchy ingredients that inforget rn cause it was march that I was told about it. I guess it's delicious and it's working it's way north and east and gaining solid momentum as a product. There are also a lot of really good and not too difficult recipes for cheese substitute at home. Like a strategically brined and crumbled tofu isn't too different from cold feta for example.
