If you are going to run with your stroller I would definitely get a BOB. Its the only way to go. Pricey, but well worth every penny. I have a single bob & now a double b/c I have 2 kids. I used to run in HS & was planning to get back to it. I've run with the bob a few times & it was very nice. I don't run very often due to lack of motivation, but the times I did I was glad I had the bob. You get what you pay for.
I had a snap & go & loved it with my first kid. It was easy & convenient. With my second I just used the double bob for everything. It was so easy to push, could hold both kids and hold my stuff.
The down side to the snap & go is that you can only use it with the snap in car seat. This means that it will only be used for a year at most. My son was so big (90th percentile) that by 6 months he was to heavy for me to carry around in the carseat, so I stopped using it & switched to a regular stroller. Which I then had to purchase. I bought a maclaren umbrella stroller. Again, a pricey choice, but well worth it. You can push it one handed, which is very useful at times. One reason I had to get the maclaren is b/c I am 5' 10" tall. Most of the other stollers had lower handles, so I had to bend over or walk funny to use them. I personally like umbrella strollers b/c they take up very little room in your car, so you never have to remove them.
If money is no object...get a BOB for running, a snap & go for the first year, and a maclaren (or other nice compact/umbrella stroller) for use after the first year.
If money is an issue...invest in the BOB. You can use it all the time. You can buy a car seat attachment bar, so you can clip the carseat to it, just like a snap and go. Or the seat does recline and you can use it like a regular stroller. If you think you might use the BOB as more than just a jogging stroller, make sure you buy the Revolution model. It has a front swivel wheel which you can lock (for running) or unlock for everything else).
Good luck with your decision
