Disclaimer upfront as a caveat emptor: I have tinnitus in both ears so YIMV (I'm coining a new "artiest" warning, becasue we need one for subjective things like sound quality so YIMV = Your Interpretation May Vary)

I have ST 2.5 and 3, Dim Pro, Rapture Pro (which brings in Dim Pro now - and Kontakt 5 and UVI, and...)

Yes I think ST 2.5 is better. But Dim Pro has ability to do some nice analog synth work plus some of the add-ins are nice, even some stock sounds are perfectly fine but ST 2.5 is, IMHO, BETTER "on the whole."

Note however, if all you have is the very small sampling that comes with ST 2 free than NO Dim Pro is MUCH better becasue, Dim Pro comes with a FULL library and it does have some good sounds. ST 2.5 also came (no longer sold only ST3)with a full library if you bought it, as does Kontakt 5 if you buy it: you get what you pay for!

But beyond SOUND differences they are DIFFERENT "synths" structurally. e.g., ST 2 can do 16 FULL patches at once - Dim pro, becasue they are actually elements of sounds not necessarily individual patches, can only do four parts at most without another instantiatation of Dim Pro.
