Congratulations to all new admits! Well done!
Regarding JBS vs SBS, jhere are a few of my thoughts:
JBS extends until September, too, not July. Summer term allows lots of options, but the deadline for submission of your individual project (thesis?) is in August-September, as far as I've understood.
Cambridge core program includes a global consulting project, which to me sounds pretty much like the Oxford summer option "strategic consulting project". This project takes you all over the world, depending on which company you choose to work for.
For someone like me, with an academic background, core courses are a good thing. If you know the basics, you might benefit from more electives. For me, the health concentration option is an important focus point.
Regarding career service, why do you think the one in Oxford is better? Where did you find out about their funding? I would really like to hear more, since I haven't really paid much attention to any differences there.
My personal pros for Oxford were larger class size for better networking and course options, slightly higher ranking, cooperation together with the Institute for Science, Innovation, and Society. Cambridge had the health concentration, the science/medical sphere around the university, a smaller, perhaps more intimate class size, and a more appealing city and school atmosphere. As you can see, all these differences were minor and neither school stood out. The choice was difficult but I went with my gut feeling.
You have to come back in Oxford for a two week Capstone project while in Cambridge you can do a short project and be done with the course by end July, while leaving the school in end June.
The endowments (mainly the Said family) of SBS are far bigger than Judge and this reflects in the admin help the school provides in career services in terms of sector consultants and career service experts and orgainsed treks.
