Mechanical disk brakes are easier to modulate than Hydro brakes; hydro will activate extremely fast, and if you have a panic situation you could be flying over the handlebars before you have a chance to prevent it.

As you said, mechanical disks are easier to maintain and cheaper to maintain, less tools needed, no need to use a wedge tool to keep the caliper open when you fix a flat. The only drawback to mechanical is that they are not self-adjusting. I had my TRP Spyre C Dual piston brakes mechanicals for about 2,000 miles, I have yet to adjust them. Hydros are not superior to mechanicals in stopping power, stopping power of both has everything to do with your tires adhesion to the pavement, or surface, it has nothing to do with one being one type vs another type.

Some will give me flak about what I said, but watch this video:

Another thing I saw on a test was that more expensive rotors do not make any difference, and metallic pads don't grip the rotors as well as resin. The single best upgrade you can do to any type of disk brake is going with 180mm front rotor, and just the standard 160 in the rear, that means whatever brake system you buy make sure you can at some point switch to a 180 front rotor. My bike came from the factory with 180 on the front.
Just wrong on basically every point. Had trp spyre with good pads and non compressible brake housing and they are crap compared to even more basic hydro brakes.

Modulation on hydro brakes is better. You also have much more stopping power and can use the brakes with one finger giving you much more secure grip on hadlebars. I've never used a wedge when removing a wheel, why would you do that? Just don't squeeze the lever without a wheel in.

More expensive rotors are usually lighter, sometimes more durable. I've tossed cheap shimano rotors before due to uneveness of the braking surface which gave vibrations. No issue with icetech rotors.

Metallic pads have some advantages. Stopping power is more than sufficient with hydro brakes, they work in the wet just as well as in the dry, are more resistant to fading and last much longer than organics. Organic do have more initial bite.
BS, I don't come here to argue. Have fun talking to yourself.
