I've always preferred the sound of a speaker closer to straight ahead, rather than toed in (or with very slight toe-in). I generally find this produces a smoother, more filled out sound, more dimensional soundstage, etc. With decent off axis performance, image focus can be good as well.
One effect of toe-in I've never liked is how it tends to squeeze the sound too small.
I did listen to a set up not too long ago (Magic A3) with the severe toe in some are recommending - crossed well in front of the listener. It "worked" but I frankly didn't like it quite as much as speakers facing closer to straight ahead.
All to personal taste, of course.
