I'm not gonna debate! I own both traps and you're free to come put your hands on them at any time and see for yourself which is built better.

The K9 extremes are made of heavier metal, they're dogless, have a bigger pan, less welds and screws, better pan tension adjustment, they come coated and they cost less than a mb650!

Those aren't opinions, those are facts!

Buy whatever traps you're happy with. Doesn't matter to me either way.
