For me, the "bloatware" issue hasn't been one I've had at all. Once I got the phone, I disabled all the Samsung apps I didn't need to use and they never popped up once afterward. Plus, with how fast phones are and the storage space these days, they might not even be a huge issue anyway. No more so than me disabling the apps on any carrier/non-rooted phone, maybe?
I've love a phone with a metal-backing too, but I couldn't really find any out there for the newer models. I think with most phones these days, you're going to have some compromises one way or another no matter what you get. Then you just have to weight what's more important... having a phone with a jack or a highly-related camera, or a nice skin/Android experience, etc.
Overall though, while I didn't go crazy over it in the store, the S9+ has mostly worked out great for me. If given the chance to get it again after the other models that have just been announced or released, I'd probably still get one.
