Welcome to the forum, Kip!
Well, flyaways are very, very few and far between, so much so that they're hard to actually list. Most aren't flyaways at all - most often they're the result of the return home function activating because of low battery, signal loss, etc..
Crashes are, well, crashes! Pilot error is responsible for 99% of them and it's about the same for all drones.
Customer service is the best in the industry, without a doubt. In fact, a log of each flight is automatically saved, and can even be sent straight to 3DR from the field if required. Speaking of which, the warranty can't be beaten either.
I've only flown a Yuneec once - a friend has one. Nice enough, but in my opinion Solo is hands and shoulders above it (and above DJI, for that matter).
I'm not putting down the other drones. I own a Phantom 3! But I assure you, I get far, far more enjoyment from my Solo. It's a little "picky" to be sure, but everything is being addressed by 3DR and it's now behaving pretty much the way it should.
You just can't go wrong with a Solo in my opinion.
