You are likely to get differing opinions but I like the factory stuff, especially when it comes to diagnosing (if needed) and availability /cost of parts. get stuck somewhere on a roadie with that MSD and your up schitt creek without a paddle
LOL, 6AL's are everywhere in every town. Much more likely to turn one up than you are a Mopar style ECU at a parts store anymore. When you do find one it's an overseas unit that probably won't work very long if at all. Things aren't the same as they were 10 years ago.
The things that make the MSD head and shoulders above the Mopar unit is the additonal features. It comes with a rev limiter that you can tailor to your needs and you can plug in things like two steps and timing controllers. I can adjust my timing from the drivers seat.
