While I understand the sentiment, the thing is you do NOT get twice the Bessa's quality when purchasing a Leica camera. Hard to quantify, but it's probably more in the 1.2x range.

That said, I really like the manual focus tabs on the lenses and the mechanism on the Q looks interesting. The Q is also newer so likely has a few improvements, but in general Leica has always been a bit behind the likes of Nikon, Sony, and Fuji in terms of electronics and firmware. Where they win is build quality.
