The 2.5 is the long lived/classic Volvo engine (redblock/whiteblock), it's well known for long service and durability, although does require some PVC and timing belt work around 100k or so. Do note there were some oil ring issues impacting 2012/2013 models of this engine - high oil consumption. This engine was used after the new 4 cylinder (2.0 Drive engine) release as it could support AWD, all front wheel drives got the 2.0 once it was ready. I believe the 2.5 is only paired with the 6 speed auto where the 2.0 has the 8 speed and a significant MPG increase.
The 2.0 are the new drive-e engines that rolled out mid 2015, it's the newest/latest Volvo engine (direct injection, electric water pump, timing belt) that they have put into service across the complete fleet. There were some issues with 2015 and high oil consumption (piston/rings), there's a TSB and a serial range you can check to see if in/out of this range. Some folks had issues with pinging, there was also a TSB for a spark plug change in the 2015/2016.
I've owned one 2.5 and currently own two 2.0's (still work on the 2.5).
My take: The 2.5 is a fun, if dated engine, produces great power, has an odd sound/vibration (noticeable) that I like - but many don't. Cared for and not overheated these engines can put up impressive mileage. The wide engine does impact turning radius of the cars it's in (not great). I've been super impressed by the 2.0's - they are vibration free/smooth, have decent power, and the MPG are amazing. In our S60 and V60 we can get 34 to 35 MPG on long trips at decent speed (AZ speed limit is 75). The 2.0 do have the new stop/start feature which is not well done, but easy enough to disable/defeat. Jury is still out on how these engines will do long term, but I feel pretty good - I understand it shares a number of internals with a diesel version in the EU, and Volvo has put all it's bets on this motor. It also appears to be easy to work on, although our two have been flawless thus far.
Hope this helps, let me know if you have any further questions...
Take care,
Scott
