Yes mate, but let it settle down for a day, you will definitely notice a difference. I think it is much more reliable, if you need to go out of the town then I would try the normal version, you want to avois issues, you don't really need to reinatall the rom, just flash kernel and wifi mods.
The fact that it's' not overclocked doesn't mean that it is the same as the stock one from SE or that its not going to be smooth.So in my opinion I prefer to sacrifice overclocking for stablility-reliability.
