I hear better things about Chaos:Child, but you may want to temper your expectations going into Chaos:Head. I haven't personally seen it, but it's no where near Steins;Gate if most people's reactions are anything to go by.
As far as the rest of the season goes, there are a bunch of cutesy shows I'll be giving a chance but am unsure about. I'm most excited for the sequels (KonoSuba, LWA TV, and SGRS) and what look to be somewhat mature seinen/josei shows such as ACCA (really promising staff list), Onihei, and once again Shouwa Genroku Rakugo Shinjuu S2.
Fall had so many good shows I'm still behind on, but I'm excited for the Winter season nonetheless.
