Yeah, there's five isekai series this season. Choyoyu is the super-generic power fantasy, Shinchou Yuusha and Kemono Michi are both KonoSuba-likes, NouKin is CGDCT, and the book one is something entirely different
I read what was available from manga for "Average" girl and it was ok, though i didn't feel like waiting for more. Maybe I'll give anime a shot. I didn't really like some of storytelling choices in it.
A bit of the anime is already out, and it's pretty unlike the source material. I feel like fondness for the anime is going to be unrelated to fondness for the books or manga
Other stuff:
Azur Lane is... alright. Kind of erratic in both storytelling and animation. Does have some potential yuri in the form of Kaga appearing to be in love with Akagi
NullPeta is decent. Animation could be better and I don't think there'll be yuri, but it's funny
