I could be wrong but I believe they are essentially the same engine. I've seen good and bad luck with both. It seems like when you get a good one they are very strong but if you happen to get a bad one then they can be a headache. Either will fly the plane very well if running good.

I'm looking at the same airplane and can't quite decide if I want it for sure. Well, I should re-phrase that. I definitely want it; just can't decide if I should go ahead and buy it.
