dd axel motor vs dd hub motor, how much better is axle?

What's an axle or axel version? I've never heard of that.
Also, wouldn't it be easier to get direct answers to your questions/help with your project if you just posted a single project thread, and stated your goals and needs, and let us help you figure out what the best thing would be for that?
You'd get more specific and useful help than starting a bunch of separate threads in different forums about related topics that would be better answered the other way.

He means a shafted motor versus a hub motor.
It all depends what you're looking for. Either kind can use regen braking, but only at the penalty of not being able coast freely. A shafted motor allows you to change ratios and speeds easily, but brings with it the adjustment, noise, and maintenance of a chain or belt. The weight of a hub motor will always be in the wheel, which reduces the effectiveness mechanical suspension. On the other hand, it frees up spaces in the bike to carry batteries and electronics.
Efficiency can be good (more than 80%) or not very good (less than 70%) for either type. A shafted motor can be lighter. A hub motor is almost always simpler and easier to install.

Axle motor= shafted motor = external windings = inrunner
DD hub motor = stationary axle, = internal windings = outrunner
The axle motor,will always need a drive system (sprockets, chain , belts, or gears, etc) to transfer the power to the drive wheel. Any of those will always have efficiency losses.
