Okay, so good question here, and you aren't the only one with confusion here.
Now I understand that at this point in your life your big concern is to "get a good job" which to be honest any of these diplomas can get you!
but to best choose it's good to understand the difference.
So first, let's look at the difference between MBA and MiM as opposed to MF courses.
The main difference here is that MBA and MiM are "General Management" courses.... you do a bit of this a bit of that - negotiation, stats, international business, leadership, etc. etc. to get an overall "Business" diploma in management. The two main industries that draw from Bschools are Finance and Consulting (although there are plenty of other industries too).
MF courses are basically MATH-based and technical. Meaning, these courses are made for numbers-geniuses.. people who like numbers problems, etc... Often within the finance industry an MF or MBA can lead you to similar places.
The next difference is WHEN you do the course. For an MBA 3+ years of experience is recommended. It is designed for people who ALREADY have a decent amount of work experience, and NOT for the fresh grad (so not for you at this moment, although maybe later)
MiM is essentially "An MBA course for people with little experience". Similar coursework, similar structure, but it's for folks with no experience. MF, being a technical course can be done with either no experience, or with lots... people with a few years experience tend to have stronger profiles when applying but plenty of people with little or no experience go also...
Ultimately you need to choose what is best for you, and if you aren't sure, or like both types of degrees, no one says you can't apply to both MF and MiMs!!!
Soooooo, that's our "nutshell"

Hope this helps you out!
