What Build to use?

[JustusIV]

So i just pulled my HTC 6800 out of retirement. My gf phone is toast after less then a year and we still have a year to go on our contract. Personally i would be pissed if i spent a hundred bucks on a piece of electrics that didn't work for a year and believe me someone would hear about it. Anywho she is content with using my old mogul that sprint said they would hook up for free. I have been out of the game for a long time and proceeded to download the ppckitchen and notice a lot of builds so i was wondering what one is fastest most stable for a lady that will use it primarily as a phone.
I grabbed three when updateing the kitchen 21903, 23569, and 28014. Like i said looking for 100% stable and and quick as possible
Thx
