These won't decide it
Three things to check first
Both are 3D chairs in the same $1,000–$2,000 band, so the mechanism does not decide this pair. The capacity and the carton do.
Curbside delivery leaves the box at your curb. The Quantum carton is 59 in long and 191.8 lb; the Champ II carton is 48.4 in long and 211 lb.
Both publish the same warranty line and the same free curbside delivery with a paid white-glove upgrade. Check the current terms before you buy.
