CM 10.1 is pretty stable on our device. You can take the one from ADC-Team or from davidteri. They are both stable and have a good performance. If you want a more 'stylish' looking rom you can try Ehndroix III or for example SlimBean with inverted gapps.
CM 10.2 by davidteri is also stable but doesn't offer such a good perfomance as CM 10.1. If you want to play games you should use a Gingerbread or ICS rom, because the Jelly Bean graphics drivers are crappy. The best thing would be if you try different roms and choose the one that fits you best.
