Not justifying the bloatware, but at least you can hide, disable, or delete them. There are a lot of useless Apps on my iPhone, and that list grows, and I have no choice only to fire up my phone and find new Apps installed on my iPhone all the time. But instead of being able to hide, disable, or delete, I have to maintain a folder called "useless crap" that I dump everything into.
You fail to mention a few positives, the best looking screen on the market, blazing fast speends, NFC that works at many many many more locations than Apple Pay, and OIS that the i6 does not have. Not to mention a better battery, etc... if you ask me I'm moving from the i6 to the S6 (even maybe the gimmicky Edge - has slightly better battery and screen performance than the S6).
