I use Ubuntu 20.04 just as I have used 18.04 and 16.04, and the presence or absence of snap doesn't alter the experience for me. GNU/Linux based operating systems will always have a sort of idiosyncrasy inherent to it that stems from the fact that it's really isn't built on fads, and fads are always what would detract from it. Hence, Snap should be used by those who like it, and history will tell us whether it were a fad or not.
I think Ubuntu in general tries to appeal to more of the masses and would try to use things to draw people to it. Nothing wrong with that; you could always use Arch.
But please don't regard a feature that really isn't forced on you by GNU/Linux in general as a reason to, eh, be snapped off it. I use Xubuntu 20.04 and have used Snap here and there and for the most part I couldn't be bothered by whether it works well or not. I do think the topic of whether Snap makes sense, whether it's too slow, etc., is a valid topic to discuss, but I don't see how it should be an argument for or against Ubuntu.
In any case, being for or against something, when really it's only your own business whether you use it or not, does always have a sort of political tinge reminiscent of the aforementioned proprietary operating systems.
