Heya, Vaishali,
Well, to be honest, yes I would. The Bee, cool as it is, feels outdated as it is much larger after folding, and without a leg rest, it is not as comfortable for naps nor for that age when the child has longer feet that the base of the seat but doesn't yet tough the footrest. Also, no footrest when facing the parent, meaning dangling feel. I personally am not completely into the Bee's design, it doesn't seem as practical anymore, especially with better and more foldable options out there.
The Triv seems cool on paper, and I like the chunky wheels and the nice padding, though multiple parents reported the stroller not being stable, and tipping rearward, which is most probably a design flaw. Even without that, I find its seat shorter, and less toddler-friendly than the Mios', and so I would stay with that. I personally had it for my third (but the first gen ;-)) and was surprised it was really sturdy, maneuverable, and could take my older (4yo at that time) as well (tight fit, but a fit).
