ND - set the correct exposure at your slowest iso, plug in a remote and put it on burst. Merge all the images later in ps.
Grad - Do it in post, or if you must do it properly, take a bracketed shot and fade one shot into the other.
Starburst/andromeda/soft focus/split image/etc are incredibly hard to replicate in post so they look like they should.
polarising/colour polarisers are next to impossible to replicate in post.
