I want to start Gurren-Lagann, but I'm facing a dilemma.

I can either download RMVB videos and watch it immediately (and I mean, within five minutes) or wait 30+ hours for my MKV/MP4 torrent to finish for episodes 1-6.

The thing is, I've been watching RMVB and AVI, and not thinking twice about it since it was fast, but recently, I watched an anime that was in MKV format, and I was really surprised at the difference.

On a related note, what's the quality difference between MKV and OGM?
