Reply to MIDI Fighter or Kontrol F1? What does each excel with?

So.
I'm really really new to DJing, only been active for about 4.5 weeks. I'm currently using only a Traktor Kontrol S2, Traktor Pro 2.5, and KRK Rokit 5s (have already worked one fraternity party, cause I'm just a college kid, and they provided the PA system and some odd large EQ device for extra control).

Now I'm not trying to get ya to go and listen to my stuff or advertise/spam or anything, but here's my soundcloud IF you believe listening to what I've got + reading what I have to say will = a more..."informed?" response..

http://soundcloud.com/emacmusic (like in the most recent track in my spotlight tab, you'll here "WORK" shot in there, and that was used from a cue in one track, but I'd rather turn that into a sample for the remix decks to utilize that track space better)

Anyways.
Being so new, I've mostly been working on beatmatching, doing sets/mixes, and really really basic stuff. But I've toyed around a bit and have been really interested in remixing and mashups. I put one up on my soundcloud (two sort of) and I used the sample decks but it was really hard to honestly utilize it without any sort of controller.

I'm decently proud of that mashup, but I feel like I can really expand and get creative if I have more analog/MIDI control over traktor and its functions.

So finally, my question is this:
I'm looking into buying either a MIDI fighter or Kontrol F1, in hopes of being able to live remix/mashup and use a lot of loops or single shot samples. Which is better for my situation, do you believe, or which is the better device in general??

I may be able to answer that on my own if somebody coud really explain to me what the MIDI fighter is and how it is possible to use it in a setup. It looks really cool, and tons of fun, but I've never been really sure how it's to be implemented in a set? Same with the F1.
Sure I can read all about them, but I do really well when people sorta explain it in laymans terms.

If I need to clear anything up, lemme know.

Any and all advice or responses are very much appreciated!
Look forward to hearing what people have to say, I'm having immense fun with this hobby right now and I hope with a better understanding of the hardware I'm interested in, I can turn this into more of profession as time goes!
