Yes, definitely not double. In fact, they aren't actually better than other top end competitors, they are just a bit different, which gives enough wiggle room for fanboys to claim something "magical".

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.
