I've only used one of them, so I can't give a fair personal recommendation. (Sorry, but my "to do" list is way too long these days...) But from what I've heard and read from tons of people, either/or would be a good choice. There's a lot of difference between what User A-G say and what Users H-P say. In the end, what works best for you is a matter of trying both and deciding. Unfortunately, that really is the only way. It's more expensive and time consuming, but in the end you'll be much better for it - running 2 awesome products and having 2 great months!
Good luck in your decisions. If you need any help on the MFX front, just let us know. We're always floating around somewhere! :cheers:
