Width of the tyre is not going to be a major factor. Unless they are 19 or 38- the two extremes. Type of spoking on the wheel will affect the ride- Radial spoking-direct pull from the hub to the rim instead of crossing other spokes- will give a harsher ride, but still acceptable unless you are on rough roads all the time. If you have any inclination to road riding as your main form of Masochism- Then get a road bike with the drop bars. You do not have to ride in the drops and if you look at a road rider going past- He will probably be on the Hoods- on top of the brake levers. And if you got a straight bar bike- then it will not be right in a few years time.
You keep coming back to the Tricross. Get a test ride and see if you like it. If the riding position is too awkward and uncomfortable- then go for the Sirrus. These two, along with the Sequoia, are not going to let you down.
Remember though- the main thing is fit. It it doesn't feel right- then try another bike. Or another size.
