The coil pack has the *theoretical* advantage of no moving parts.
Also, one coil or drive transistor could fail and let a six cylinder
engine limp home. (not sure about a 4).

The coil packs have been notorious at flash over during humid
conditions, which then burned carbonized tracks into the insulator.
That same sort of thing could happen with a single coil, but with a
single coil there is probably more room to allow a bigger flash over
path. Your description of running badly with humidity made me think
of my experience with coil packs.

Let's see if that new computer fixes your car. Good luck.

If you can start then, I would still look at the engine in the dark
to look for flash-overs on coil, distributor or wires. If the
weather is not foggy, make your own fog with a water mist.
