I have run my SRS in 3 matches - hardly a huge sample.
Here is is what I found. The SRS is an extremely accurate platform, so in many stages where the distances get stretched out or you're isolated to one magazine, the SRS is awesome. The biggest issue for me was simply changing magazines. When you're on the move or need to change magazines, the size of the mag well is so slim that it can be difficult to quickly insert a new magazine accurately and smoothly.
There are also some challenges in alternate positions. When shooting weakside, I have to come off the optic to run the bolt. Also, when running the bolt in alternate positions, things can get a little clunky with staying on target. It does take more body motion to run the bull pup bolt just because it is "way back there".
Now, I know for a fact that all of this can be trained up and with the new, well functioning 10 round mags, the SRS can be ran well in a match. It's just a function of whether or not you want to dedicate the practice to learning the system. After running it in those 3 matches, I ran a traditional rifle in the next match and felt my management of the rifle itself was much easier.
So, small sample size and I am not overly experienced, but if I had to choose a rifle SPECIFICALLY for PRS style matches, it would be a traditional design. BUT, I will never get rid of my SRS for a whole other list of reasons.
