I have Galaxy installed on one of my PCs and I only occasionally use it, most of the time not.
I haven't really noticed much of a difference using it, compared to how Steam or Epic Games launcher or the EA client or UPlay works for me. They all do what they are supposed to do I guess, download games, install games, let me buy moar games (I haven't done that on Galaxy but I presume you can do it through there as well), run the games, automatic updates, cloud saves... So far I don't recall facing any major issues or annoyances on Galaxy (or those other clients for that matter), but maybe my use is so lightweight that I just don't face them, or my expectations are so low.
Most of the time I don't use Galaxy, simply because I don't have to. The only real use cases for me to using it (instead of offline installers):
1. Online multiplayer games. I am not playing such on Galaxy at the moment (in fact the only online multiplayer game I have played like... ever... is Team Fortress 2 on Steam, and lately I've dabbled a bit with Counterstrike 2 and Overwatch 2. Oh yeah and I did try out Fortnite on Epic Games too but it wasn't really my mug of vodka either).
2. Brand-new games and especially in-dev games that are constantly getting new updates that I'd have to update manually with offline installers, in many cases reinstalling the whole game. Then it would just make more sense to run them on Galaxy and let it auto-update them. However, I rarely play so new games where this is an issue, so...
I guess a third use case would be if I played some game constantly on several different PCs, and wanted to keep the save games in-sync between those PCs with cloud saves. So far I haven't had this need, I do play on several PCs but I simply tend to play different (single-player) games on them.
