Ozark trail ridge, explorer, vibe, salom 2, schwinn axum pro x comparison?

What one has the better parts, especially gearing system, bearings, rims, shocks/forks? And does weight, shocks, tire size and width matter much when just riding around town as far as peddling, grip, roughness? How much skinnier of tires can you buy for each

Also, with the salom 2, do back shocks effect riding as far as activating when not wanted? And how does it compare to a seat shock? And would a back shock bike help with a child seat in he back as far as not being bumpy? Any child seat recommendations?
