Both are a going to be more difficult without assist. The problem is they are hub drives so all that weight of the motor is placed in something you need to rotate and rotational weight is the worst weight to have to move.

I would highly recommend looking at the Specialized SL line up. Nice and light well integrated with a mid-drive motor made in conjunction with German brand Mahle. I have a Vado SL especially 6.0 or something (it has been semi customized with electronic shifting and better brakes and some other nice parts) and absolutely love it. It is not bad pedaling without assist but it isn't great but way better than my R+M Supercharger 2 but that has two batteries and weighs a ton. If I wanted less weight the Carbon Creo would be excellent for that and can be swapped to a flat bar set up (we did quite a few before the Vado SL came out) but I like the Vado a bit more, especially being more upright and having the ability for a rack.

You could also look at bikes equipped with the Bosch SX system or Fazua which are two other lightweight mid-drives. I haven't had time with Fazua yet at least not enough to render opinion but I can say Bosch generally knocks it well out of the park however I have yet to try the new SX system (which is their lightweight motor battery set up)
