AFAIK all you're missing out on from the 15 is the cruise control and DVT. Can't go wrong with any of them honestly, tho.
While I could have sprung for a DVT model and could have either tried to sell or trade-in my 2013 S (either would have resulted in me taking a huge financial hit), I opted not to do so. The newest Multi is sweet, no doubt, and I was strongly tempted, but I'm glad I didn't. It still does everything the 2015/16's do, albeit without the extra frills (DVT, BT, back-lit buttons, etc.), and most importantly, I have a rear brake that worked correctly from day one.
Owners of the DVT models are by and large still having teething problems with their bikes, and this is something that, already having been through once, I do not want to go through again.
