I've just switched, about a month ago, so here are some things I have noticed:
- I miss the stock Samsng messaging app. I liked the way it worked for sending group texts as individual threads, and the delay send. I have found a close replacement in Yaata, though.
- I miss the water resistance and durability of my S5. Yes, the MXPE is water resistant, but you wont find any videos with people dropping it in water or the torture tests you see on the S5.
-The camera app and pictures are better on the S5.
Now, past these things, I wouldn't go back to my S5.
The Moto has a much cleaner Android experience. I don't have to reboot it every other day like I did my S5, with all it's bloatware.
Moto Voice - Love it! Especially compared to that crap on Samsung , S Voice.
Battery has been much better on the Moto, but that may be because of age of my S5 than anything else.
Pull the trigger. You'll be glad you did....
