Both bows have advantages and disadvantages. For longer range shooting (over 20 yds. by my definition) the longbow of 64" or more is generally more accurate, smoother, and more comfortable to shoot.
For those shorter shots under 20 yds or for shooting in confined spaces (thick bruck, pop up or ground blind, etc, the short hybrid of 60" or less can work rather well for most archers.
Of course, your draw length, shooting split finger or 3 under, bow design, etc. can figure into the equation.
I draw 29" on a good day and have found the 60" Griffin, 58" Centaur, and 56" Brush Hawk by Cascade are my favorites, but I do know my limitations with these shorties.
