The RS3 is a good bit better than the R3 IMO. The difference is an improved tweeter. The R3 was pretty good, but the RS3's tweeter smoothed out the slight harshness and dryness the R3 had.
Rega's speakers are very good IMO, but they're not a universal recommendation speaker. They're a bit different from the norm, hence why most Rega speaker owners also use Rega amplification and sources.
If you're into Rega's philosophy of how music should sound, you most likely will love them. If not, you'll probably not be able to live with them for the long haul.
All IMO of course.
