Lovefabs are a bit less.
It makes a big difference honestly. If I was putting together a setup, theres no reason not to go with top notch parts. Otherwise, spend the same amount and get a Revhard kit or something. There's no point in piecing together a kit if youre not doing it:
a) the junkyard way
or
b) spendin big dollaz on premium shit
Otherwise, youll save a lot of time/hassle by just buying a predone kit.
