The reason to buy Google phones direct from Google, No BLoatware, I dislike all the samsung Bloatware, Sony, same thing, HTC well they are not too bad. But I bought my nexus direct to completely bypass the bloatware, imho if you want to avoid bloatware buy direct!
I use a purchased app called textra and it has built in stage fright protection, for 3 bucks its totally worth it. Not worried about stagefright at all. Also its the best texting app i have ever used lol
