Word on the street is that stock COP are the most reliable.

Don't waste money on Accel or Granatelli. I'm currently using msd coils, so if you want to wait a few years and thousands of miles, I'll let you know how they hold up. I was getting a misfire under load with my stock ones. One of my accel coils just up and quit on me with no code.

The car runs better with aftermarket coils, but so far they have not lasted long for me. 1-1.5 years for my accel coils. I'm pretty sure you will gain some power as well.

My tuner won't install aftermarket coils or warranty any engine work done on a 3V with aftermarket coils already installed. That's all I need to know. I also had my own well documented bad experience with Granatelli coils before I started going to this tuner.

Side note: I did gain power with aftermarket coils, but nowhere near enough to be worth the headaches.

I need everyday driver dependability.
My car is a 4.6, Edlebrook Gen 3 SC @ 8psi. AR long tubes ,race cats and Bassoni exhaust. Underdrive pulleys,3.75 diff. Alum. drive shaft.
I am guessing she is around 485 hp.
What would you do next for HPs ??

More boost. Block is easily good for 12psi.

The only time I give a thumbs-up for aftermarket COPs is when someone is SC'd as you are. But even then, I'm hard pressed to mention any that are reliable. I'm hoping that someone can give us positive feedback for a change as opposed to the tons of bad press we've seen and heard.
