Although I own a very similar Roberts R9924, I ordered the 925 Sports as well, just to compare them. I found that FM and LW are about equal on both, but that MW selectivity is actually better on the 925 Sports. Here, in the west of The Netherlands, Radio Mario on 675Khz interferes with BBC5 on 693Khz on the R9924, but on this 925, I can separate them easily.
The sound is fantastic for such a small radio; it can play louder than you think. Robustness is excellent, as I dropped it a few times on a concrete floor with no damage at all (neither to the floor, nor to the radio:)). The LW section is the best part of this radio: it is the best LW radio that I own (and I own a lot...). From my location, I regularly listen to RTE1 from Ireland; reception is not perfect, but decent enough to enjoy their good programming. BBC4 is received like it is broadcasted from a few miles away; it's that clear. During my recent holiday, I took it to the east of The Netherlands (an additional 100 kms eastward from my location), and I still got decent reception of Ireland.
If you like longwave radio as much as I do, I highly recommend this radio! FM is quite good as well, while on MW, it is not the most sensitive radio. It's not really bad on MW, and it's an improvement over the R9924, but there are better MW radios out there.
As a bonus, battery life is unbelievably good.
