My interpretation:

Rhino has tons of muscle mass, not armor. The time stomp  thingamabob  is a show of this strength. In our world, having a relatively high muscular strength implies a low muscular endurance level, therefore slightly lighter armor + slower speed. Warframes have been hinted at (or has it been confirmed? Not sure) being composed of infested flesh. They may have a similar thing going on.

Valkyr may be simply ignoring the damage rather than wearing thick armor. She has that berserker gig going on.
