Is there something better about using an open-ended wrench over an
allen wrench?

On an old garage sale bike, the allen wrench approach was how I got a
very difficult pedal off. 6mm on a ratchet with a cheater bar. But
there may be tricks to holding the cranks and pushing on your typical
wrench that I don't know.

It may work, but an allen head is not as strong as regular wrench flats. Pedals
can be hard to break loose, and there's a good chance the allen head will strip.
So use the stronger, 15mm wrench flats, and leave the 6mm allen for emergencies.
