Hardwood and tile flooring project. What to do first?

I am redoing the tile in my entryway and installing hardwood flooring adjacent to that. Which do I do first? the tile or the hardwood? And why? Ive had conflicting answers from installers. Also, the tile was installed directly onto the floor, no subfloor. Im sure its best to remove it (im dreading that!) and redo it properly onto plywood or any other options??? Thanks for any input.

1. Remove the tile first and make sure that you have a fairly smooth surface to deal with. Some wood flooring will have a foam pad on the back of it so you can put it directly on the exposed ground. If not they make a pad to put down first. Then start to measure and cut your pieces to fit. Its easy but time consuming. I just did my neighbors living room and dining room.
2. I'd do the tile before the hardwood floor because once the quick set gets on any surface without your knowledge it will not come off its very hard to remove quick set once its dry. also I'd use a concrete board under the tile it absorbs any water/moisture without ruining the board.
3. 1 do the tile first,reson tile bits and thinset,grout can make a mess of your new wood floor get the dirty work done first then start the floor.
