Hi Keym,

yes, Keil is the best.
Its most economical on consuming code ROM and also data RAM and also fast.

I prefer using it in a DOS box.
So I have no experience with the IDE.

The only disadvantage, its dongled. And this can cause many trouble or reducing the compile speed extremely on Windows NT.
Also if you work on a notebook, any dangle stuff is inconvenient.
Maybe the problems now solved, but if you can, try to get an undongled version.
