Vuly Ultra 2 vs Thunder 2
Both are round Vuly trampolines rated to 330 lb, so the choice is the spring system. The Ultra 2 uses coil springs at a lower price; the Thunder 2 uses Vuly's leaf-spring system, which keeps the springs out of the jumping path.

What matters most
The price gap is real: the Large Ultra 2 is about $449, the Large Thunder 2 about $879, roughly double. For that you get the leaf-spring edge design and a 10-year frame instead of the Ultra 2's 5-year frame. The trade runs the other way on the springs themselves, where the coil Ultra 2 carries 5 years against 1 year on the Thunder 2's leaf springs. Both share the same 330 lb limit and 5 years on the mat, so the decision is whether the safer edge and longer frame cover are worth the extra spend.
