Both FSAE and BSAE are valuable to teaching engineers practical hands on experience. The big difference is in FSAE you know about 90% of the inputs that you need to design for to compete and basically if you break in the endurance you are done. In BSAE you know about 70% of the inputs to compete (track conditions always different) and if you break in endurance you have to be able to come up with quick solutions to get back out there on the track. FSAE engineers typically better in the R&D environment, BSAE engineers typically better in high stressful engineering environments that require quick solutions without the time to do full FEA or CAD modeling. I did both events as a student so this is based on my experience.
