Hearing HTC owners talk about how all the S4s software features are gimmicks is quite sad. It's anti innovation, regressive rubbish that thus far in the past has only been adopted by iPhone fans (for obvious reasons).
Essentially it's the kind of attitude that green lights software laziness. I for one am glad Samsung continues to innovate on this front, I've had enough of the treat consumers like technically inept children and over simplify everything a la iOS attitude. I'm confident that of every 10 new features Samsung introduce, there'll be at least 3-4 useful ones. Drama shot, direct call, wave to answer in loudspeaker, beauty shot, gif capture, dual camera video and still shooting, global translator, sound adapt, air preview in videos, split screen multi tasking, group play, wifi direct and s beam transfers etc etc. These are all genuinely useful features that I have used in the past or even routinely use.
If the features aren't your cup of tea, that's fine, but don't blindly refer to them as gimmicks, especially if many people find them useful, and even more so if you've never even used or experienced them.
On a side note, you may prefer the HTC One's screen on preference, but scientifically the S4s screen tops it, at least when it comes to accuracy of colours, contrast and black levels. In movie mode the S4s screen is closer to the 6500k standard (among the closest of any phone out there), the Ones screen by contrast is several notches too cool. Add to that the S4s screen has near perfect black levels and contrast, along with better viewing angles. The One is slightly brighter and the smaller screen might help make non 1080p media (eg non 1080p Gta III) look better, but otherwise the S4's screen size could be seen as another advantage seeing as how physically the phones are roughly the same size. The PPI differences are pointless since you can't see the pixels on either, not without a magnifying glass anyway.
