NPA, while Netscape is far more configurable than IE, if you do not need these attributes, stay with what you are comfortable using, the performance difference will not be noticeable. Either will do the job for you.
I would suggest you even stay with IE4 unless there is some reason to change. Computers are the one technology where the "if it aint broke, dont fix it" truly applies.
