Yeah, I think I have to agree. I'm at a similar stage to where you are.I've tried to play High on Life but it's really not good. Shooting gameplay is boring as enemies have little differentiating between them and there's only one gun (and knife) to use till now (almost finished the second stage). The dialogue is hit and miss with it's humor, even if it's funny though the gameplay makes the overall game boring.
I'll still continue playing to see if it improves but a pretty average game thus far.
Loved Halo Infinite and still feel like turning it on eventhough I've finished the campaign to finish the side quests. The difference in gameplay between that and High On Life is huge (I know HOL is also about it's humor but like I said it can't compensate).
Also starting Senua's Sacrifice so that I can complete it before the sequal comes out.
I tried persisting because of all the positive praise it got on release, and the prologue was pretty cool, but the gunplay and enemy variety kills the gameplay.
