The 2.5's are some of the latest and greatest shocks to hit the market, whether you would benefit from them depends on how aggressive you ride. If you just cruise around not really pushing the limits, dont jump or ride fast then the 2.0's will be fine. Once you get more comfortable with the machine and start riding harder the 2.5's will really shine. They have a lot more adjustment, wont fade in the whoops, wont bottom out on big jumps. They are no negatives with going with the 2.5's, I myself would rather have to much shock than not enough and wishing for something better.
