Honestly coming from someone who has watched the entirety of Konosuba at least twice and really adores the quartet, you really feel like the humour just becomes so forced at times.
I know the take of it is an Isekai Misadventure but it really just gets too much, you wish it could just slow in pace. I'd recommend Princess Connect as it's basically Konosuba with food and a slower pace.
Demon Slayer, has that part of worried about it not living up to the hype.
I'd keep the idea of trying Zombieland Saga. It's very different as it's a comedy horror/idol anime so it is a very unusual taste. However I was proved wrong completely.
