The Samsung ROM was horrifically slow and ugly and filled with unremovable apps I didn't want, plus it contacted the AT&T mothership constantly even though I don't use AT&T and the phone is unlocked.
So I wiped and downgraded to CM10 stable. This one lets me make calls, but randomly reboots at least half a dozen times a day.
I assume you are talking about the AT&T Galaxy Note using the quincyatt rom.
The Jelly Bean versions all have severe issues, especially with the camera app; however, if you go to XDA developers forums and use a custom ROM based off of CM 10, you should be okay.
For myself, ICS was the most stable version... but even then, I had some really tough times until I upgraded the modem firmware.
If you are having rebooting issues, try doing a full wipe (including /system) through TWRP and then fresh installing (do not use any backups of your apps) a ROM. One additional procedure I tried which may (but probably not) have helped was to let the phone do its initial boot without touching anything. Let it sit for a few minutes and then reboot it. Once it boots back up, then go through the standard setting up procedures.
I finally got my Note to be extremely stable but battery life was still a problem until I tried the Blackstar ROM. I should check which governor it uses and see if CM will also save as much battery power.
Good luck sir.
