I'm not entirely sure what either of the bikes you mention look like, have you got any pictures? They need not necessarily be of your own bikes, but it would give us something to go on.
There are lots of factors that effect how a bike feels, tyres have quite a large effect, heavier, fatter, softer tyres with a more pronounced tread pattern will make a bike feel more sluggish than lighter, harder tyres with little or no tread. Frame geometry and stiffness, a more flexible frame with "lazier" angles won't feel as sharp as something stiffer with quicker steering. Then there's the overall weight of the bicycle, while a couple of pounds either way might not make a huge difference to performance, unless your racing, it can effect the way a bike feels, particularly when climbing or accelerating.
