I use mostly CA except for things that need epoxy, such as firewalls. CA is hard to sand once it's fully cured, but if you sand it within a few (up to 20, say) minutes of applying it there's no problem. Plastic modelers use CA as a filler, and that's a use that requires sanding and one in which you don't want to sand off anything but the glue itself. Not that there's anything wrong with Titebond, but if you find CA more user-friendly there's no reason not to use it.
