Currenly using Midnight, and it really is stable being overclocked @ 1.5Ghz. No problems with calls, MMS,MSM Or Data.
Used Mobsterz unSENSEable, it is fast, and what I truly miss about it is the speedy/buttery smooth UI, the Jellybean Contacts and GoogleNow.

It was lacking a basic features like "Update Profile" on settings, which I used a lot when I can't make or receive any phone calls.
While being happy with it, It came the day when my phone wouldnt make or receive any phone calls, I tried so many things like; rebooting, powering it off, removing battery, restoring it and nothing seemed to fix it; I only needed "that" so missed feature "Update Profile" to fix the issue, but it didnt have it, so I flashed Midnight and everything worked from that moment on.
I have had the need to "Update Profile" to get a MSM to working only twice in 3 days. It looks close to stock, but it's faster and more realiable.
