Sure - but even on those basics, Epic Store isn't great (eg. controller support is less than great, shop interface is clunky, slow, and difficult to navigate and shopping experience is one of the slowest/obtrusive of any active store (not just on PC). Possibly only beaten by Switch in that respect.
IME (obviously both of us are just anecdotes) download/installs are among the slowest of PC stores I use (somewhere between UPlay and Origin, which both tend to take forever).
But there's other QoL things that are really bad - eg. offline installs/behavior is basically just designed to irritate/frustrate, (though again, a touch better than MS store in that respect which is just completely broken), and I could go on. I mean 'ignorance is bliss' is easy to say if there's no alternative options that work better - but on PC there are tons, also most also have better libraries, so it's not like I'm missing out* on anything by mostly ignoring Epic.
*I understand Epic has pretty decent $ deals, so maybe it works out on that level, but since most PC options nowadays are already very cost effective (least of all, even Microsoft, thanks to GP) it's hard for me to say if that's worth putting up with other problems.
