Best Drop kit?/ Best Drop Shock?

[Orange77]

I started off wanting a small drop a 2/4 just to level the truck but once i realized i probably would want to go lower and eventually bag my truck a 4/6 drop would make more sense and set me up for future bags. now im curious to know who makes the best 4/6 drop kit and as far as shocks goes what shocks are the best lowered shocks to go with. If it means anything right now i have 17in rims with p275/60r17s all around but would like to eventually go with a 20x8 in front and a 20x10 in the back. some pics of your 4/6 drop with 20s would also be nice with the specs on the wheels as well.
