The fabric capacity of the 3750G is 32 Gbps, and of the 3750E, 160 Gbps; but there's also forwarding performance to consider such as the 3750G tops at about 38.7 Mpps and the 3750E at about 101.2 Mpps.
Why the difference? Well besides, as Collin notes, the 3750E supports dual 10 gig, the 3750E series supports more (2x) stack ring bandwidth and the switch is targetted for Enterprise usage (the 3750 series more for SMB.)
BTW, the 3750E series Stackwise+ is "smarter" than the 3050 series Stackwise.
Oh, and vs. other vendors, when we speak of "stacking" switches, insure you're really comparing the same feature. Some other vendor's stack feature is Cisco's cluster feature.
I think the biggest difference is that the Cisco's are both fixed port. There are no real modules to speak of. It's all ethernet. And like the other guy said, the management can be done through a simple console port although most have web-based GUIs now.

looking for early feedback from customers befor...
