Depends on situation, FBO for average street/strip car who wants somewhat factory look (me btw). MSD for more strip then street time. That's how I see it. The new MSD Digital E-curve is something to take a look at.
Careful here, there are multiple people who seem to blindly agree with Don @ FBO. He's a good man who knows his stuff but also a salesman.
I'm running a FBO system and am happy with it.
btw: I had a MSD dist that said 'MADE IN USA' on the box brand new. I take it out and immediately read MADE IN TAIWAN on the shaft bearing. FBO is morally against Chinese parts, like I am.
