I use Dolphin Mini and it's still the champ of the lot, IMO. 
I do have to say that more evidence supporting the every droid is different is that I am the total opposite regarding what makes my OG purr. I don't really play games on the phone, but I am on the interwebs a lot and for decent stretches. 
I have for a while been going no compcache period, and I used to be addicted to compcache. Swap partition with swapper2 set to swappiness of 80 and sometimes drop to 60.
And this is where I am out in left field, VM Heap 60.
I have had many a post explain why my set up was bad, but none on why it made my OG run so damn smooth. I have no explanation for it, but I know what my Droid tells me. I was in a little film you may have all seen, The Droid Whisperer. Yep, that was me, and to tell the truth, it really is an honor just to be nominated.
