I'm gonna say try something else!
Hardware wise the samsung phones are really decent, but in my opinion they are way to plastic-y and feel cheap in the hand. That coupled with samsung's horrible interpretation of android with all of the touch whiz stuff annoys me. It uses too much ram and bogs the phone down. They also don't even run 4.4 kitkat yet.
Try another phone like the HTC One, it feels solid and has near stock android, with HTC sense, which is more intuitive and clean in my opinion, and is overall a more attractive, solid phone that to me screams quality
The one downside is the lack of micro sd expansion, which is addressed in the newest htc one that was unveiled this week.
Note my opinion is biased, I have a few samsung mobile devices, and touch whiz annoyed me so much as it ate up all my ram and the Samsung apps were useless and stupid that I spent a whole day and learned how to put cyanogenmod on my device. So if you go with the samsung device, look into cyanogenmod as a cool upgrade to make your phone stand out from the rest
Good luck finding a phone!
