08/09 Optional ABS but no Linked Brakes. In really hot weather the fairing design cooks your legs. Has a "glove box" on the tank. Has TPMS sensors that you can change the batteries in.
10-15 ABS, Linked Brakes and Traction Control. Fairing redesign to reduce heat on legs. Glove box on left inner fairing + factory heated grips. Added ECO-Mode for better fuel economy if you stay below 6000rpm. Can change batteries in TPMS sensors on 10-12 models but somewhere in 13/14 they switched to the potted sensors.
15-22 Windshield with vent, shorter 1st gear , better Linked Brakes, several other minor changes.
I've ridden all 3 "generations" and prefer my 08 simply because I find the Linked Brakes too intrusive in how I ride. I do have ABS and it has saved me on a couple of occasions.
However, mine has been extensively modified over the years, so the comparisons may be unfair.
Also, where I live (UK) heat is rarely an issue.

All are pretty reliable with hundreds of 100K+milers out there as well as 20 or so 200k+ and 2 (that I know of) 300K+milers.
Yes, things do break and wear out, but better than most bikes.
