the techno is quite bigger than the quest and therefore pushes differently.
it was hard to get used larger macs once i fell in love with how the quest and volo pushed, but i've settled for a love of the frame sizes between the quest and techno (these would be the vogue and ryder - which i don't believe you can try out in any store, unless you live in NY or CT and can visit a mac showroom).
since you're talking about the techno, though, here's my quick review - they're taller, have adjustable handles (though i don't like the rubber-y handles on them as much as i like the foam handles on all smaller macs), and they have an awesome canopy that can zip-down to offer even more protection. it also fully reclines. if these are important features to you, than the larger wheel size and weight difference won't be an issue at all, but the wheels and weight mean that they steer slightly different than the quest. i'd say they were still easy to steer and one-handed steering is still definitely possible, it's just different.
i had a quest first and tried out volos in the store well before i moved on to larger macs and i eventually settled for a volo and a vogue (because i can't afford to replace the beloved ryder i never should have sold). the basket size is about the same in all of them, though the more lightweight the stroller, the easier it will be tip it over if you hang anything from the handles and the child exits the stroller. this is avoided, now that my child is three, by telling him he cannot get down until i remove my bag(s) and yes, even the largest umbrella, the techno XLR will tip if overloaded and the seat is empty, this is an issue with all macs, though big fans of the steerability, ease of use, and lightweight factor (like me) will say that's worth noting but not too big of an issue. i've never had a mac tip with my child in it.
