Who has priority on a taxiway?

Whoa guy! Right-of Way is assigned in 91.113, and there is nothing there
that gives airplanes right-of-way over helicopters.

2) A glider has the right-of-way over an airship, powered parachute,
weight-shift-control aircraft, airplane, or rotorcraft.
(3) An airship has the right-of-way over a powered parachute,
weight-shift-control aircraft, airplane, or rotorcraft.

Doesn't the ordering here imply it (at the least)?

Does anyone disagree that the general idea here is the less
maneuverability options an aircraft has, the more right of way it has?

Maybe it's not fair for gyrocopters, but helicopters can go up, down,
sideways, and backwards -- or hover. They got more options than
everybody else.

Speaking of helicopters, on my checkride one kept popping up and down
next to the runway I was using for all the landing assessments. There
was lots of corn growing, so when he was on the ground you couldn't
see him. I took off on a x-wind takeoff and he suddenly popped up at
the far end, where I was heading. He hovered there practicing not
drifting onto my runway. It was a little disconcerting because from
1500 feet away he looked awful close to my centerline.
