I own a Tero X 6.0 and ride a similar mix to you. I routinely use about half the suspension travel (although I have removed the tokens from the front; stock it would be stiffer and use less travel). It's probably mostly due to riding on/off curbs and flying down hills with rooty asphalt, though. Not due to the offroad parts. I will say that the R&M way of advertising suspension makes a lot of sense to me--the tires stay on the ground all the time. You can definitely feel that in turns when the rear wheel is unsettled in some way. It's just a blip and the rear wheel is planted again.
I also live in a hilly area and I use all the gears of the Tero X. It's basically impossible to go much over 28MPH on it, though, not because of assist limits, but because that's already a 90 RPM cadence in top gear. The Vado would be biased toward speed. I'd probably need more assist on hills to make up for it, but I'd go faster on the road.
Based on your requirements, I'd say the main downside of the Tero X is that on-bike storage is really limited. The shape of the frame and the suspension eliminate most of the frame pack area you might have. The large travel dropper rules out a lot of seat bags and probably also trunk bags (assuming you added a top rack in the back for a trunk -- it doesn't have one stock). Only one of the bottle cage mounts is really usable. Both bikes have similar issues in the front (you need a kit that straps to the fork).
