I don't know where do you got 29.3 from, but as far as we are talking about lbs and not kg ;-) you can judge this yourself.
29 lbs is a usual Creo SL weight (1-2 lbs less with light&expensive road parts, 1-2 more for gravel use).
Vado starts at about 32-33 lbs naked and about 36-37 lbs as EQ.
The Como SL is about 45-46 lbs with front rack and basket.
My wife and I tried Como SL and Vado SL. You see&feel that the Como SL is the heavier bike but it's still much lighter&better than most other ebikes of this type "low city comfort". You can easily loose two pounds dismounting the front rack+basket and one more with smaller tires. The rest of the lbs is shared between frame, handle bar stem combo, rear hub, bulky frame and mudguards+rear rack. So you get something for the extra weight, more comfort and easy of use for example with the geared hub. The question is what the rider wants&needs.
As my wife is very small&light, I "pushed" here to the Vado SL. Also I hated the upright and fix handle handle bar stem combo of the Como SL and found it bad at higher speeds. But feelings&needs of my wife are different, even if she sees&feels the advantages of the Vado Sl, she felt good on the Como SL and felt the bigger comfort. Also the position on the Vado was much too "sporty" for her and we had to change the handle bar to one with more back&up sweep and rise. She is somewhere between the two, the Como SL a little bit less bulky and normal (adaptable) handle bar+stem would have been her's.
I wouldn't make the decision due to weight. It depends on your wife, if she is light and used to a sporty position, not much suspension and normal gears, the Vado SL is her's. If she is bigger and prefers bikes "grandma's style", the Como SL is her's. If she is somewhere between like my wife and your salaries are better than ours, take both! ;-)
Just try/ride both!
