I feel confident saying 21A is a standard footwell. The only possibility for 20 is that it's larger.
Either way this is highly academic mate! They're both either very good (or bad) seats depending on your preference for that type of mini cabin. Essentially 77G, 35G, 33K, 33E all have the same mini-cabin dynamic. Potentially nice and quiet and private, moreso than forward cabin and on its best days the mini-cabin is awesome. But also last served, frequent cabin intrusions from PEY and Y, and IME even sometimes self-upgraders. It's a difficult part for the cabin crew to patrol and the rear galley blocks their vision.
To answer my own question, there's no discernible difference in footwell size between 20A/K and 21A/K.
Agree that the mini-cabin is very intimate. However, row 21 does suffer from increased noise and light from the PEY cabin during the midflight meal service, but nothing major.
