Enternity here as well.
I believe because of all the Sense 3.5 elements, it's a hair slower than others.
Mine is OC'd to 1.2 with Lagfree Governer.

Rock solid. I've dabbled in every ROM out there.
BAMF does make a solid ROM. DroidTh3ory was making killer ROMs.
I have a backup of ProTekk's updated CM style ROM to go just because...
In my opinion, Eternity and BAMF SonOfAB ran very similar in speed/performance and reliability.
Patiently waiting working Data, Phone and sms/mms on Twisted/DroidVicious ICS build...
All the ROMs you mentioned are solid. But the right one for you is like asking you what kind of car/truck you drive.
Backup, try 'em...only way you'll know.
