This is indeed a conundrum I face daily.

What I have found is if you can stay in overdrive, do so. This will of course entail a speed bleed, otherwise you will downshift and it's all lost.

Accelerating I would think take somewhat less power than going uphill because you are not fighting to go uphill. I can push my car up to probably 3 mph with leg power on a flat surface, but I can't budge it on even the slightest incline.
