Welcome to the Forum!
Daggo is right. You need to provide some more details to make a fair comparison.
In general, unless you are talking about a Tuff Country lift most lifts will provide some benefits. Some kits are optimized for flex, some for road manners, smooth ride and some are just good all round but not the best in any specific driving condition. The RockKrawler and MetalCloak are specifically designed with flexing in mind but they are not a budget lift.
