Your budget is a huge factor in this for type of lift.
Branding is mostly anecdotal, whoever got burned is a brand hater, if it's running with no issues then the brand is god-head.
Consider: Kings, Icon, Fox for top of form coilovers with plenty of upgrades and tunability. Anything Bilstien/Toytec will be an upgrade from stock, but have durability issues and no significant tuning/upgrade/maintenance path only a few hundred less than the big boys. Also consider where you send them for rebuild, local manufacturer would make this easy.
OME and Pro Comp are stiff b¡tches that make cornering, load bearing better and everything else worse $600-$800.
Spacers will get you the lift for a couple hundred.
