016 or 014?

I'm sure this has been talked about a lot but I cant find any real back to back comparisons. The question is: If you put the same decent driver in both cars which is going to be faster the Swift 014 or 016? and why? Also, which is the better car maintenance wise? parts availability, engine rebuilds (think I know the answer to that one), ease to work on etc? which is the car to have if you want to be nationally competitive? opinions, feedback, comments all welcome....

Thanks,

JP
