Search is fine for my uses. It doesn't have the facial recognition to quickly search for all photos of a person but it looks to be tagging things in an accepta le manner and I've found the things I've been looking for.
I used their free trial - 1Gb of storage available for a year iirc - to try out a few things but then ran in parallel for a while and now have stopped syncing my new photos to Google. Good luck with whatever you decide!
