I gave Immich a fair try, but it could not replace Apple Photos for my use case. YMMV, but my favorite Photos app features simply weren't available.

I use Apple's top-notch editing for all sorts of stuff - RAW images, videos, basic enhancements, etc. When I tested, Immich didn't have very good, if any, editing features.

I also love Apple's search functions, and it Just Works™. I'm sure Immich has similar, but I know it would take a lot of processing to make it happen.

I also did not really care for Immich's UI, it felt overly basic and Material Design to me, but that is only personal preference.

Another gap is metadata. In Apple Photos I can tap the little "I" icon to see a lot of capture metadata, and in Immich I did not see an equivalent to how good Apple's one is.

It’s less than you think! Consider that Apple’s image recognition happens on your phone. Also, it doesn’t matter if indexing is slow, as long as the photos are indexed before you need to search for them.

I used to run Immich on a 2nd gen Core i3.
