I would argue that rewrite is slightly more difficult then refactor. Refactor means, after all, making the current system better while rewrite would mean no update/change/feature on the current system and more pressure to get it done. I would herby say that a good team with experienced people will succeed in both cases while an less experienced team will probably have a higher chance of doing a refactoring then a rewrite. I like refactorings better. It allows me to optimize a system slow and steady. I like rewriting better if you don't need to support the old env while doing the rewrite and having expierence in the old system.
