> Point-to-point microwave latency should be the same as fiber latency at the same distance.
Actually, it's often less because the microwave travels in a straight line while the fiber has to follow the utility poles or trenches (which often aren't in a straight line due to right of way issues). High frequency traders performing latency arbitrage use microwave dishes instead of fiber because it's a fraction of a second faster than using fiber connections on a cross-country connection.
Microwave dish systems are, however, a nightmare to support because transmission can be affected by the weather, birds, and a whole lot of other things. They also aren't very high bandwidth, and if you have a lot of dishes that means a lot of interference. I'd say they're perfectly fine for things like extending your LAN to your cabin up on a mountaintop, but not great tech to run an ISP off of (though people still try).
