The differences between the two are pretty small. The G Pro is a little bit more hyped, with just a bit more energy in the bass in particular. You can see the differences in these Rtings measurements.

I like the sound of both of them a lot, and I wouldn’t call you wrong at all for going with the cheaper G Pro. I think Logitech knew exactly what they were doing with their slightly cheaper price point. :)
