Subject: [EE] longer distance data link - CAN or RS485 or ?

Just wondering if anyone has an opinion or has learned the hard way, the
best choice for a 50 to 200 foot data link.  Presently its being done
RS485, but is that the best choice? Its not multidrop but point to point
and preference is to use CAT5
