The pads last much more than V-brake shoes on my friend's bike.
The point I was trying to point out was different. With disks braking

I have a set of hydraulic disks on my cross bike. I absolutely would NOT say that they had "improved" modulation. I would say that they have greatly increased sensitivity - to the point where it is too easy to over-brake on a light bike.

Tom, can you tell us what hydraulic disk brakes you had/have on your crossbike?

My old MTB is my commute bike, shared paths bit of gravel in places tarmac
etc! Pads last thousands of miles literally years, the New MTB at best a
few months! Worse a few red rides, they are toast.

That's true -- particularly with the resin organic pads. You get less stops -- but they're really GOOD stops. It's like small portions of fine food. You have to savor each stop -- starting it slowly and letting it build to a crescendo of deacceleration -- and then release, letting the pad linger against the disc. Mmmmmmmm. Would you like pepper on that? A digestif?

On a cross bike? I thought hydraulic Avids were MTB only. Are they cable discs?

So before any long ride, be sure you've loaded your bike bag with spares.

Nah, just fit different pads. But if you did want to take spares, they
are very thin and light, so no inconvenience.
