How to convert 30p to 25p in Adobe Premiere CC 2014?

Hello Everyone!

Many thanks in advance to anyone reading this. I have shot footage on a Canon 5Dmark2 in 25 and 30p and need to put it into the same film. I have found that Media encoder can do this. But is twixtor better? Or is there some other advice anyone can give me?

Is it better to go from 30p to 25p or vice versa?

Many thanks!

Kind regards,

Robert
