I have the 2013 16x19 (have only had it for about three months) and recently got the 2015 16x19. I think both the 2013 and 2015 versions are fantastic racquets that have good power, spin and even pretty decent control. Both are also solid and stable. The differences between the 2013 and 2015 versions are slight but noticeable. The 2013 version has a more direct and raw feel while the 2015 version is more plush and a little softer, it also feels like it may have a slightly larger sweet spot. I would also say that the 2013 version feels a little brassy while the 2015 version does not feel brassy at all. I enjoy the feel of both but prefer the more refined, plush and softer feel of the 2015 version. I get similar power and spin from both versions. The 2015 version may feel slightly more forgiving, but for some reason the 2013 version feels like it may have more plow-through (probably because of the slightly higher swing weight). I would say that both have pretty good touch. I have not yet figured out which has better control, but would guess that it is pretty similar. I have added a leather grip to both and customized them slightly to make them 12.1 oz with similar swing weights.
