So if I was just going with a complete motorized experience, it seems like the direct drive is the easy winner, because it's faster, it's easier and it's more efficient. The problem is that i'm reading that direct drives ruin the pedaling because they're too heavy and I still want to be able to pedal.

So my question is how can I get direct drive and not ruin the pedal experience and if I can't, how can I choose between a mid and a geared rear hub? I suppose I want the option to either pedal or use the motor and I want one where you can put a stronger batter in to make it go faster than advertised.
