Performance ignition coils?

Buddy of mine asked my opinion about high performance coils he's seen recently.
I have not tried any of them but got to looking at some and was wondering if they were any good.

My usual reaction would be to use a mopar replacement but I figured I would see if anyone has any experience with any of these...

They are all around the $45-55 mark.

More juice is always good.
Standard coils are built good enough and cheap.
So if all you want is good enough and cheap then stay stock. If you want to spend a little more and get a little more then go with the upgrade coil.
Don't expect to all of a sudden get neck snapping acceleration, in fact you might need an emissions test to actually see any difference between coils.
That said I had an accel super coil in my mustang and upgraded to an HEI system in my current YJ. I believe there is enough diference to make it worth the extra $$

That being said, the coil, wires and gapping a plug wider will give you a hotter spark to fire a cylinder with a little oil leak or a worn injector.

I had an accell in mine years ago and found them to be very unreliable. I went through 3 of them in 2 years and then switched back to oem coil.

Can type or like the one pictured above?

My Accel was the big fluted can type and it lasted through years of abuse, high underhood temps and frequent steam cleaning (I had a steam genny at work so why not use it )

I currently have the accel and it has worked fine for the last 3 years. Stock system is pretty good but I was building the motor from the ground up so I just went with the accel.

I use a MSD box. Use the factory box as a stanby. Use a Ford HEI Coil. You can get the coil for about $5 at the junk yard.

I've been running the msd coil on my stroker for 5 years now. Not a single issue yet, a good many of my buddies have had their stock coils die n then leaving them stuck in the middle of no where n I've had to bring them a replacement. I'm plenty satisfied w the msd one.

I've ran many on all sorts of apps,
I'm currently running an Accel Super Stock unit.
While they provide a hotter spark, another advantage is how they're "potted".
For lots of off road use you can go with an epoxy potted coil over an oil filled unit.
Nothing wrong with the oil filled units, but in some cases heat + high vibes can lead to the coil swelling from oil expansion and killing your spark until the coil cools back down, but this typically is the canister units...
The issue with modern coils (stock/aftermarket) is they are extremely prone to failure when shorts occur.

I have a MSD street fire coil. So far no issues. My gaps are set at .05 but i also run a 6a box. Ive had no issue with the coil. I didnt realize my carb was really rich until I found my plugs were completely sooted. Still had no driving issues.
