I just did a 2500 mile trip in June on my '06 Sprint with a buddy that rides an '04 VFR. Both of us ran with stuffed saddle bags, tail bags and tank bags from Inverness, FL to Clarksville, AR for a wedding. I had 210 miles on the clock by the time we both met up.
The Sprint has a good bit more power (more cc's), better gas mileage/fuel range by a bit, is lighter by a few pounds and is more comfortable to me.
The VFR has bigger bags, better handling and better headlights.
The Sprint elicits more comments on its looks by the public. The VFR's style grabs me almost as much as the Sprint though.
If you want more power, especially down low, go with the Sprint. If you don't have a Triumph dealer close, go with the VFR.
Really, the bikes are a toss up and each have their strengths and weaknesses. Both would serve you well.
A test ride would be the only way for you to decide.
Bikes are like shoes, some fit and some don't.
