I have had my 2016 15" MBP with 1TB and Radeon Pro 460 since launch. I actually enjoy the feel of the keyboard and I am still on the original keyboard. Some of the keys have occasionally gotten stuck but I have managed to fix them with some pressing, tapping, or wiggling of the keys. This has happened maybe about 4 times since I've owned it. I am a software developer and often times work in Windows using 3D modeling programs such as 3Ds Max and Unreal engine, etc.
I also have done some long sessions of gaming like OverWatch and Destiny 2. It has handled both games extremely well, better than I expected actually, being able to play over watch on high settings as well as Destiny 2. Keep in mind that I don't play these games at the screens native resolution otherwise it would perform badly.
The battery life under macOS is acceptable to me as long as I'm not working in a game engine. If I'm coding away in XCode and running the iOS emulator then I get maybe about 4-5 hrs of battery life, depending on what project I'm working on. After two years of use the battery is at about 94% health, which I think is pretty good. The one big draw back about the battery/power adapter is that under full load the battery will drain rather than charge. Makes me kind of sad.
I have both enjoyed and hated the new larger trackpad. There have been moments where I have appreciated having the room to drag a file from one side of the screen to the other without running out of room on the trackpad. On the other hand I have had incidents of the trackpad registering my palm/thumb as a touch while typing and thus moving the cursor to another position. This can be quite annoying but I have been able to adjust my typing habits to minimize the phenomenon.
I have had one issue with the speakers and this happened rather recently. I woke up my mac from sleep (macOS) and it immediately started playing this loud and fast popping sound form the right speaker. I quickly shut off the computer and booted back up. I then checked the speakers while playing some music in iTunes, sure enough the right speaker is now audibly quieter than the left. I plan on getting this repaired with apple care but just haven't found the time for it yet.
Overall I am pleased with the performance of this laptop, the new vega MBPs do look appealing but I am happy with my purchase so far especially coming from a 2008 Unibody 15" MBP. Maybe in a year or 2 I will think about upgrading.
