I honestly like Nakyup better than Stock + Tegrak.
I used that combo for a long time but switched.....Nakyup just seemed to have more options (over clock was easier to use).
Only thing I miss with Stock/Tegrak is VooDoo sound....Although, I have found that with Nakyup, the sound does seem better and louder than just stock......
You dont have to set everything up again....There are tons of apps out there that allow to to back everything up before hand and then restore after the flash.
You don't lose anything and everything stays the same....
Best one so far is Titanium Backup (pro version)...lets you back up everything to Dropbox or to an external card.
But check the market or do a google search for best backup app....you'll save yoruself hours of work.
I know about backup apps but setting up system settings like alarm, ringtone and the folders in the home screens is a pain...
