[X Style (Pure) General] MrTriTanium:
Depending on how you use your phone and how each phone handles battery life, the rate of charging might not be a factor to consider. If you burn through battery (and/or the phone itself helps) and can't get a days worth then fast charging should be important. If you don't use your phone much, turn radios off, etc. and charge your phone when you are asleep then either method of charging will do. Neither phone has wireless charging so you'd have to look elsewhere to get it. Feel is totally subjective and ONLY important for your tastes/wants. The screen is a contentious issue as some don't see a difference between 2k and 1080p, think the increase is worth the battery hit, or other reasons specific to the screens compared. If DxO is to be believed then the rear sensor in the Style is something to be reckoned with.

In real life usage, the 808 or 810 should be close to each other. The 808 is only "missing" two "Big" A57 cores when compared to the 810. The real difference is in benchmarks where having the "missing" cores will show better scores. With an almost stock Android interface the Style should show no feeling that "it needs more." I have no experience with OnePlus (or Moto and their OS optimizations) phones to speak on how Oxygen OS behaves. Since both phones aren't out to buy and be reviewed, any talk beforehand is just speculation. Wait for reviews from people you trust for an opinion or get a hand-on yourself on the UX "feel."

The amount of RAM you "need" or "should have" is debatable. If you play a lot of games and switch between heavy RAM-usage apps (or a lot of them) frequently, more RAM is beneficial. The type of RAM is cut-and-dry. LPDDR4 is simply better than LPDDR3. AS A STANDARD LPDDR4 operates at faster speeds AND uses less power than LPDDR3. Whether OnePlus has taken full advantage of the benefits has not been disclosed and no one has a device to find out the speed their RAM runs at for a definite conclusion.

USB Type-C is the "cable to end cables" when properly implemented. Full stop. Type-C was created with USB 3.1 and ALL of its benefits come with 3.1 AND software that enables those features. For the actual cable, Type-C brings a reversible plug (like Lightning) so there isn't a correct way you can plug the cable in. USB 2.0 (most likely in the Style too) will max at around 20 MB/s when transferring files to your computer or another device, and will be slower for smaller files. USB 3.0 and 3.1 will transfer at MUCH faster speeds with larger files. You can learn more about 3.1 and Type-C here and with a quick search. Other Type-C features aren't worth discussing as neither phone can take advantage of them.

Contact-less payments are supposed to finally take-off with the launch of Android (and Samsung) Pay to give that "extra push" to retailers that this is a feature that most would take advantage of when consumers can. Honestly, Apple Pay sowed the seed for contact-less payments. If contact-less payments is something you can see yourself doing then the OnePlus2 will not allow you to do so. Speaker quality or stereo speakers is a nice feature to have and should be considered if you play any media over the speakers. I have no comment with eithers' Costumer Support reputation.

For me, the decision between the OnePlus2 and Style is a no brainer. The OnePlus2 makes too many concessions against OnePlus' OWN BELIEFS and against the Style to make this a hard decision. Which is why I'll be replacing my G2 with the Style at some point this year, unless the new Nexus phone(s) are compelling enough ;)
