The Prusa is great, especially for folks who are getting their fist printer, it's the most predictable if you use their software too. CR-10 results are as good, you just have to dial your filament settings, but then Prusa doesn't have settings for every filament either :)
LM has been great but the hot end assembly came with leaks, it wasn't tightened down correctly. I need to go back and fix that before I can review it. Otherwise it has been great :)
For budget prusa clone I went with the A8, I am upgrading the body to metal frame (AM8) :)
