Is the Asics GT-2000 or the Nike Structure lighter?

The GT-2000 15, by 1.5 oz in a men's US 9 (8.9 oz against 10.4 oz).

Can I switch from the Asics GT-2000 to the Nike Structure?

Yes, but ease into it. The drop moves 2 mm (8 mm on the GT-2000 15, 10 mm on the Structure 26), which changes where your foot loads at landing. Give it two weeks of easy running before a hard session.

Which is more cushioned, the Asics GT-2000 or the Nike Structure?

They are close: 37 mm of heel stack on the GT-2000 15 against 38 mm on the Structure 26. Foam matters more than the millimeters here (FF Blast Max foam with 3D Guidance System against Full-length ReactX foam with a Midfoot Support System, no Zoom Air).

Which comes in more widths?

The Structure 26. The GT-2000 15 runs in D, 2E for men's sizes; the Structure 26 runs in D, 2E, 4E.

Which costs more, the Asics GT-2000 or the Nike Structure?

The GT-2000 15, by $5 at list ($150 against $145). That gap narrows once either one gets a successor.

THE SHORT ANSWER

Drop is the real difference: 8 mm on the GT-2000 15 against 10 mm on the Structure 26. Coming off the Structure 26, the GT-2000 15 loads your calves and Achilles harder for the first couple of weeks. Both sit in the same role (stability). The Structure 26 lists $5 lower.
