I have to take the minority side and say while it's close...VERY close. I'd probably still give the nod to Magnum over MF. One thing keeps it close...MF's lift, and I mean that in a bad way. The fast lift while practical for capacity reasons, just doesn't offer me the same thrill as slowly climbing a hill, nerves getting more and more frayed, anticipating what lies ahead. This is what Magnum has that makes me say it is slightly (very slightly) more enjoyable than MF. You don't even get a chance to think about it on MF. You're out of the station, you're over the lift and into the overbanked turn before you know what's hit you. Not that that's a bad thing either, I just prefer the mind games.
Just my opinion, your milage may vary.
