Are you speaking of a t mobile carrier branded S5 or Note 3? Using a N5 now on t mobile as you are, id say you might be disappointed with either phone b/c they lack the N5s speed, vanilla android OS and lack of TW and carrier apps that plague the carrier branded phones that t mobile offers. I used a N4 and S3 on t mobile and was plagued by horrible reception. Im still on t mobile but with a moto x and so far it works the best ..YMMV
Even with never using the s pen there is more featured the note 3 have over the s5....battery life I would guess since the s4 and s5 battery is about the same and note 3 outlasts the s4 by a lot. 3gb of ram, 32gb 9f storage as the base model and a 5.7 screenThe main deciding factor for many people is the S Pen, which can only be used on a Note device. In my opinion the note 3 is far superior to any phone because of it. But if you wouldn't use that then the differences between the two phones are more minor.
Plagued? Lol.... Note 3 is just as fast as the nexus 5 and this from somebody who actually have used a nexus 5 and a T-Mobile branded note 3Are you speaking of a t mobile carrier branded S5 or Note 3?
