Best Windows 8/8.1 VM Solution?

What's up Apple Core, I'm in college doing software development on my late 2013 MBP 13'' and next semester I'm inevitably gonna need to run some Windows-exclusive applications and I wanna know what you guys think is the best pick:

VMWare Fusion 6 (free from school)

Parallels 9 ($40 from school)

Is Parallels worth the $40? Thoughts?
