V35 by a mile. That said I don't think there is a 2012 V35. But if you get a new V35, you will not be disappointed. They rarely jam, the same can not be said for the Rotor, and are the fastest loaders you can buy. Amazing pieces of equipment and if you get a Halo Too shell, it is also extremely durable and fairly light compared to other Halos. Its odd, isn't it, that the best things you can get are near 10 year old technology?
I personally really like my Vlo, and that is why I have kept it in my geearbag for a back up. They are consistent and work well. They are a bit odd in shape, but nothing like a curve ball to add a new factor to the game. Mine has been really good on battery use as well.
