FBO or MSD what do you use?

Here is what I have found. I had the MP orange box with an Acell super coil that a friend gave me on my sons Dart with a stock dist I curved. It ran 11.50's and he turned 6500 with no problems. He got an MSD 6A unit from a friend so we installed it and used the MSD Blaster coil. Car still ran 11.50's and ran the exact same and started the same. I took the MP orange box and Acell coil and are using them on my 63 with a Mallory dist I got cheap. I shift about 6100 in my 63 and the ign works great. I myself feel the MSD is definetly the best out there and a great system to use but for street cars running mid 11's and slower I see no trouble using the MP orange box or even better the chrome one. The faster higher comp cars should definetly use the MSD unit. As for FBO it is basically the Mopar ign but he improved it from what I hear. I have never used the FBO but I hear all good things about it. Ron
