Sirrus definitely more sporty than the trek. The trek is a more typical rigid hybrid I'd say, certainly no MTB and light and quick, but not a road bike. Although that could be helped with skinnier smoother tyres. The Sirrus is essentially the secteur road bike with flatbar. However, in the case of both, if you are looking for a road bike, get a road bike :-)
Do you have an
Evans close by, go get a test ride on the Sirrus. The frame geometry is the same on the whole range I think, go higher up, you get a carbon fork, you may get bar ends, better gearing etc
