P.O.
I have a BOB and I've never used a Baby Jogger, so I can't really compare the two, but I thought I'd pass along my thoughts about my BOB (in case they might be helpful). I got my BOB in May when my daughter was 5 mo old, so I don't have any experience running with it with the car seat in it. I had read lots about not running with babies until they were 6 mo old and had not heard about being able to do so with the car seat in it, so I was waiting... I've heard mixed reviews since about the safety of running with them in the car seat, though.
Things I like about the bob: The sun visor/shade comes down very far for good coverage (unless you are running in the early or late, then I'm not sure there is any shade that would work). On the other hand, when fully deployed it acts as a parachute! In my first post-partum race, it was fairly windy and when I turned into the wind, it was very noticeable. However, unless they put in "gills" somewhere, I not sure how they would improve this.
It is very balanced and is easy to manuever (once you get the hang of it - this was new for me, but it's easy to catch on). It is actually easier to manuever at speed than it is when just jogging.
At first I thought the handle bar was too low and it is not adjustable (I'm 5'10"), but after I realized that I was just hunching my shoulders and tried to relax and I now find that the handle bar height is fine. It does seem like this should be an adjustable feature, however. My husband is 6' and says the height is just fine for him, too.
The hand brake is use for the left hand, so I guess they assume that if you are pushing with only one hand, it will always be the left, but I haven't found this to be an issue. I switch hands easily and haven't really had to use the brake unless stopped anyway.
It folds up and opens up extremely easily. It fits in the back of my Escape with plenty of room a small ice chest, my bag and the diaper bag.
The bottom cargo area is great... I put my keys and water bottles in there while I'm running and at my race, I put my race t-shirt in there as well.
I think that's about it... other than I would like to get the rain sheild for it because I really like to run in the rain. If you have any questions, please feel free to ask.
