Both great projects I would also put librephotos to the equation with its feature rich unofficial android client Uhuru photos

All have great android apps and great Dev base

Have tried all three and also tried every other selfhosted image gallery

Photoprim is overall the most mature and complete in features

Yes it requires a third party app to sync your assets but the auto index feature if you sync to their webdav endpoint is killer. This means the proccess from the moment of taking a picture till it shows up in your photoprism gallery is “instant”

Also the unofficial android client is super great and almost android TV compatible

So

To be honest there is not a fair answer You really have to hey them all

:-)

CPU wise: Monitor load average as you load services. If it stays below the number of cores you are fine. That being said nuc 10 has a 6 core cpu Its more than OK for a barebones. For reference I’m running smooth on a raspberry400 4 GB RAM.
