I go back and forth between sense and CM7.2 Both have their advantages and disadvantages. Sense bluetooth works WAY better for me, but I like the customization of CM7 and the quickness.
Magnolia and Skyraider Zues have been my favorite sense roms and gotta give it up for Condemned's CM7 rom.
Your mileage may vary of course..
Not sure what ROM I'm running today
