WordPress or MT 3?

I want things like future post­ing, some­thing I have on my pro blogs The Design Weblog and Magazine Weblog, but MT 2.6x does­n’t cur­rent­ly offer. I’ve been miss­ing so many Saturday Slants late­ly because, when Saturday rolls around, I’m usu­al­ly on a plane. If I could write it on Thurs or Fri, to acti­vate on Sat, then life would be grand.

So, which is better–for that fea­ture and all around? Is it WordPress or MT 3?

Is it dif­fi­cult to switch to WordPress? How well will it import from MT 2.6x? I have a cou­ple of thou­sand posts and even more comments.
