Sorry for my english, but I must say one thing!!
WOW! i'm going to do a new thread like this, but you're faster than me!!
What about my NS experience?
Early, I was attracted by the upgrade, I wanted only upgrade, new Android version, i wanted only the newer version! But...
... i tried every (+ - ) possibile JB (4.1 or 4.2)
but i was never satisfacted by that. The system was often laggy
and choppy, with all the rom, also with tweaks and OC. For a long time I used HellyBean or Rasbeanjelly (with DevilKernel o Marmite) but sometimes the system crashed,other times for example, when I opened the messages app, contacts numbers not load immediately and the keyboard did not fit on the screen at once
. and this made me nervous!!!
So, after reading a post by thalamus, I wondered if go back to gingerbread would be a good idea.
... Now i'm using CM7.2
, with Franco's Kernel --> the results? --> The phone boot in few seconds ( 10-15 seconds!!), i can OC (and live OC) until 1300mhz (with JB it freezed at 1100mhz), the phone is very very smooth (smoother than first!) and incredibly stable. And with some themes everythings is Holo style. A good launcher instead of Nova? Smart Launcher (only 7mb of ram on 2mb of storage!!!)... and with GB Chainfire3d is good for gaming!
Nexus S is born with Gingerbread, and probably is better with Gingerbread too.. at least for me
Yes, i really love my phone now, and probably i will never return to the run for the latest upgrade.
