So far for me it's Konosuba and Dungeon Meshi. I've already read Mushoku Tensei and I don't think I can stomach watching it animated, but I haven't really heard much about any of the other new releases.

Yeah it was fun in the beginning, after all who never thought about being transported to another world where you ate a big hero with swords and magic?

But what the hell, I'm pretty sure there's more isekai now than other genres/settings. It's gotten to a point that if I see the tag I just move on.

Example: I just began watching Black Jack from 2004 on Tubi since I enjoy the manga.
