These come up so much and no one will answer except asking what do you intend on doing in your rig. Although I'll try to help a tiny bit.
1. Coil overs. Evo probably has the best kit followed by Rebel and maybe Rock Krawler.
2. Metal Cloak. Just rides great and gets me through everything. I know Rock Krawler, Evo Plush, Terraflex, Synergy, Currie are right there with them.
3. Rubicon Express, Rough Country and almost everything you can get from 4 wheel parts ranks down here with price and ride quality.
However, I have friends on every lift mentioned and we all go everywhere together. RE keeps breaking the most. Ones I haven't mentioned like JKS and so on is because I've never seen it or been in the rig with it.
