I felt that when it comes to suspension and handlings, budget makes an important role before we come down to brands and models.
Before we understand more, we need to know the differences between dampener, absorbers and fully adjustable coilovers.
Of course, the next question is what you want ? You want to adjust height ? ride comfort and to be able to take some hard corners occasionally ? or you want both and perhaps, be able to take real hard corners like in track or down/up hill speeding application ?
THen again, is money and budget !! Let's take the entry level budget of say 4-5k. With that, you can opt to go for a good adjustable absorber without any height adjustable coilovers such as GAB or Bilstein or even Ohlins absorbers (without pillowball mount or adjustable struts) entry levels...
But if you wants to have both of adjustable dampener + coilovers, then you will have to go for a cheaper solution such as Tein which offers a fully adjustable coilovers to adjust both Height + dampening rate at that price. TEIN of course do have their higher end versions and for track application but I'll just stop here as I can go on to HKS Hypermax 2 (ard 7K for evo), Ohlins canister (10K)..etc.
So again, is budget !
For those whom knows me, hehe... I have 2 sets of fully adjustable coilovers. HKS Hypermax and Ohlins. Feel free to sit in my car and try it out during our TT ! :)
