If you aren't going to use RAW, you might as well pack up your DSLR camera and go buy a 'point & shoot' digicam.
OK, that's a bit of an extreme take on the issue...but if you are at all concerned about image quality, then it would make sense to use the highest quality settings that you have available.
There is a learning curve with RAW files. Learning how to efficiently process them could really make a difference in how you view RAW files.
Of course, you don't have to shoot RAW...but you would certainly be missing out if you don't.
