Here is a link to a good track day comparison of street vs track tyre using MR2 Turbo's.

I guess there are three important factors that need to be thrown in. What size tryres do you need, what price did you want to pay and how long do you need them to last? I take it you mostly run in club days where you get about 10 laps per session? I've only used the Fedrals so I cant give you a comparison to what they are like against the RE or Yoko's but they are very cheap which is the biggest driving factor for me and I'm happy with how they perform on the track. I'd buy another set again when they wear out. I probably have around 300 engine horespower or so and use 255's on the rear. Federals cost me around $700 fitted for all 4. So half the Price of toyo 888.

i've been trying the federal FZ201's lately. we have tried both these and AO48's on our MRS and found zero difference.
 
The only downside with the 201's (so far) is they are a bit heavier than most competitors.
 
we have some freinds using the Hankooks on their skyline race cars and they are happy.
 
commonly find tyres ideally suited to big heavy cars, aren't idea on small light ones. 

I reckon I'll go the Toyo R888 or Kumho Ecsta V700
