I sold my EXR-3 on ebay and got the GW-7. It really depends what you want...
I personally prefer the GW-7 becuase you can edit the sounds (its basic editing) and save them, its got the two analog control knobs, its a HELL of a lot lighter, It has two pedal inputs, you can save 10 favourite tones to the category buttons which is great for live stuff aswell as the 100 (i think) performances you can have (I think the EXR-3 has only 10) and the value wheel is fantastic for finding sounds quickly.
They sound almost identical, only the GW-7 has newly sampled ethnic instruments and styles. I dont think theres as many styles on the GW-7 because theres none stored on the flash memory, unlike the EXR-3. So theres more space for compositions. The overall size is about 4 Megs, the same as the EXR-3.
Theres no cover function on the GW-7, nor is their V-Link support and no built in speakers.
I'll leave it up to you!! I'll answer any questions if I can...
