I don't see why the shorter head tube is a problem. You can use spacers under the stem, or a positive rise stem, to raise the handlebars to the same height as on the frame with a longer head tube. Alternatively, the shorter head tube allows a lower bar if you wish.
Your current upper body fit looks fine to me, as much as a photo shows. If you feel like you want more room, a longer stem will do that too.
So I'd lean toward the smaller LeMond.
Here is an idea, though. You have full geometry info on the choices? Why not draw the bikes (graph paper, protractor, ruler) and see where the touch points end up (saddle, bar, pedals) and where the wheelbase is.
