Which plane is the best for medium haul routes?

As the title suggests, I am looking for the best plane for a medium haul route (3000 to 5000 miles).

Depends, which year for example, overall, I would say B757/B767/B787/A319LR.

depend on the market size, if it's a trunk route, it will justify the need for VLA like B747 or A380

Over 4000 to 5000 miles use the A330-300 over the 767-300.

 But yes, depends on the years, route size etc. Some routes say DFW-CDG a 747 would be better suited. If the route is empty, use whatever you can on it to make as much as you can before others show up.

It's actually 2014 this year, and I have added some A332s to my fleet.

Thanks guys, for all your help.
