After looking through countless topics, I never really found anything showing which spacer is better. Or, is there even a difference between the different brands?
None are really better than the other; if anyone says a particular one is it's only an opinion because they don't really perform any actual function.
You have a couple different design approaches...
The topGunz and Daystar are pretty much identical--two steel donuts with a sleeve welded in between to create the space.
The PRG and Calmini use a big, solid piece of aluminum available in different sizes... 2" lift for 4WD and 3" lift for 2WD. PRG includes the Energy Suspension bumpstops.
It really just comes down to personal preference, budget or the flip of a coin. TopGunz are the most affordable, PRG probably has best customer service, Daystar has big $$$ R&D and mass production and Calmini seems to be hit or miss; one day everyone shows up happy and everything is in stock and ships on time and the next everyone's pissed and decides let's screw the customer and not ship anything for 3 weeks.
