Mainconcept or Canopus?

I have both installed on my computer... which one should I use if I go for speed over quality??? and the other way round (just curious)?

Thanks

 

For speed go with Mainconcept. For quality both programs are exeptional, I can't tell which is better

 

If your source is DV-AVI (from a cam for example) Canopus has better quality, MC is faster.
If your source is PAL and you want NTSC, use Canopus. Mainconcept's output can be jerky.
For everything else, Mainconcept.

 

As usual, thanks a lot jim...
