Um, it’s shorter and more direct. Plus there’s substantially less traffic than you’ll see in the Toledo-Cleveland-Erie corridor, especially if you’re likely to hit Cleveland in the daytime. It’s less urban and therefore has higher speed limits. The added bonus of being able to do a little shopping in Canada and take advantage of the exchange rate is worth mentioning too.

Growing up I SE Michigan, I always crossed Ontario when heading for New York State or New England.
I would also agree that taking I-94 (or I-94/I-69) across Michigan is cheaper than staying on the Indiana Toll Road and Ohio Turnpike. Michigan has higher speed limits than Ohio or Pennsylvania (not sure about Indiana), but (unless it has changed recently) Ontario has lower speed limits.
However,
the border crossings at Port Huron/Sarnia and, especially, Detroit/Windsor have gotten significantly hairier since the WTC/Pentagon attacks. (For a while there was a constant backup at the Ambassador Bridge.) I am not sure how that bridge or the tunnel or the Blue Water Bridge are to cross, these days, but then you have to get back into the U.S. at Niagara Falls or nearby and that can be its own experience of hell.
Before blithely seeting off to use the Michigan/Ontario route, I would wait for some opinions of people who have to cross there regularly, these days. (I don’t think you need a passport yet, but the date to implement that rule is rolling up on us.)
As for the tolls in the U.S.:
as Frosted Glass linked, Indiana will cost $4.15 in a car. Illinois cost will vary by the point at which you enter.
Ohio will not cost $8.95. There is no reason to drive all the way to Pennsylvania. You can exit the Turnipike at Exit 142, following I-90 through Cleveland if you will not be in rush hour for $5.45.
If you are concerned about Downtown Cleveland, you can continue to Exit 151 and take I-480 across to I-271 then I-271 North to rejoin I-90. The toll to Exit 151 is $5.75. (I do not advise this route between 4:30 and 6:00 p.m. but the rest of the time it is just city traffic–not a big deal.)

I-90 is free to the border of New York (including the Pennsylvania panhandle) where it becomes part of the New York Thruway.
From the Pennsylvania border to the most distant Syracuse exit is $6.93.
The calculator begins on the Thruway Tolls and Distances page and general information begins on the Thruway Authority home page
(I always hopped off the Thruway as soon as i could and followed US-20 across the back country. It is two-lane with a lot of villages, but very pretty.)
