Power wheelchair or power assist?

Manual plus electric assist gets my vote. It opens up the most options.

Using a manual for day to day stuff means your getting some exercise, you can get lifted up steps if necessary, getting into any car is no problem.

Then if you’ve got a big day or you want to try a bush walk, a farmers market that’s on grass or whatever you can slap on the electric assist and your good to go.

I have a Triride which attaches to the front of my chair and raisers then castors off the ground. It’s got cruise control, a good disc brake and reverse so it can go almost anywhere. Put some mountain bike tyres on your wheelchair and run them at a lower air pressure to smooth out the bumps and it’s even better..

And here:

That’s why the reverse gear is so handy. You get much better traction in reverse as all your weight is pushing down on the wheel.
So long as you can turn enough to comfortably look over your shoulder anyway..
