Yeah i am completely at stock
More important question:
Are you sure you want to remain on stock?
If you want to upgrade your system with Google Apps, why not do the whole remake from ground up. It will be the same difficulty level as flashing Google Apps.
I was on stock for a year or two and It's no problem once you ROOT and flash Google Apps (I did everything myself), or just use
MoDaCo's prebake with everything included.
But this is very very old stuff.
I have currently installed
VegaBean Beta 6 and it's miles ahead of stock (don't forget to read installation instructions and partition your SD card correctly).
The only problem I have with this ROM is that it's eating my battery, but stock was also eating it.
You can also try the newest
CM10.1 based ROM.
And if that just doesn't work for you, you can always flash stock firmware back (but I highly doubt you will ever do that once you go the custom ROMs way... stock rom... ewww

).
