MSD -vs- Jacobs

That is a choice I'll not make for you. You'll have to figure out if it's worth it IF it should fail and you can not get it fixed. IF I could not get it fixed, then I'd skip it just a "Just incase bassis."
Ask Accel if they'l fix it just incase.

It's an electronic/electrical device. They can fail like anyother product out there. My personal bain is MSD, I'll never ever use them again.
