I think comparing this and the Triv Next is a bit harsh. I mean, the Dragonfly, and that is why I am not as impressed even if I really like the concept, is just way too light. It is super light, which is in theory a bit plus. But it also makes rattly / not too sturdy, with very narrow wheels. It is a nice option for smooth sidewalks, malls, undemanding use, that is for sure. But if you look for sturdy, well, I would probably not go for this one.
The Tiriv next has a wider, though shorter, seat. It seems popular and feels alright, it is a nice option if you need a smaller reversible stroller - though I like the nimbleness and fold of the Cybex Mios much more, to be honest.
I do think that, if your terrain and use won't be too demanding, you will make a good choice with either of these. So perhaps just try them out in the baby shop to know ow they feel like in your hands - btw, LOADED, put a heavy bag there as an empty stroller is not a good reference for the push.
