The performance of an antenna will depend on the overall element size (length). 
 
Shorter elements will have a narrower usable SWR bandwidth.

 That depends on if you want a full size dipole or a shortened one. It also
depends on your fabrication skills and available equipment and free time.
It may also depend on how much aluminum tubing you have laying around.  In
the past I designed and built a full size 40m beam. Full sized elements are
massive, these days I am using commercially made 40m beams with shortened
elements using High-Q loading coils.
