I worked with both the 2500E and the 7500E for 6 years, the 2500E, with QA5 reels I had very few problems with at all. We had both the groomers and the rear roller brushes biggest thing with them was the belts breaking inside the covers. As far as serviceability I always found them easier than the older style cutting to service, tear down replace bearings and seals put back together and square them up no problems. Now you can run into problems with the cutting units going out of square but that is always an easy and quick fix by loosing the frame bolts and cross bar bolt and hitting the unit, you will hear it pop back into square.
The 7500E also had QA5 reels on it and the biggest problem we had with them was the reel itself would break if something was hit. I had 10 out of 15 reels break in the same place same piece of metal breaking out, we had most of them replaced under warranty. It did become more of a nuisance than a problem as with the last set that did this We just ground them out and ran it with the one reel blade missing a chunk. Never created problems with after cut appearance, just frustrating that we had those problems.
Now when it was time to replace units we ended going to Toro because of price difference and ease of maintenance. We went with Toro 3320 Hybrid mowers for greens, and just rotated the older 2500E back to do Tees and approaches. We did not replace the 7500E but they are slated for replacement in the next 3 years. Here I would go with the 5100H due to better after cut appearance. You can get the same after cut appearance with the 7500E but you need to get the short back rollers
