The only time I use the regular brush is when I'm in Quick Mask mode and zoomed in several hundred, or even thousand, percent, creating a mask.
If one remembers that everything is a line, even a circle which is just a bunch of short lines, it's easy to mask things (like hair) while zoomed in, in Quick Mask Mode, and using the Click, Shift Click function to do straight lines using pretty much whatever tool you're using (brush, eraser, pen, etc.).
