Regarding the ease of use, new cv2 interface has improved far greater, and it is really easy and fun to work with cv2.
But what about speed?
I made two small code snipplets, one in cv and ... |

lambda makes a function. It's an expression and so can go places that a normal def statement can't but it's body is limited to a single expression.
my_func = lambda x: x + 1

Air density alone has a fairly substantial impact on speed, if all else is equal (and if my calculations are correct!)

At 300 watts, at 10*C, ... |
