I've had both setups in my -SE.
I wasn't too impressed with the MSD. It didn't feel any more powerful, and it was expensive... And took up a LOT of space.
The 2nd gen upgrade was cheap, easy and took up little space. I also felt it ran smother and stronger with the 2nd gen upgrade.
Plus there's the new 2nd gen ignitor trick too:

It'll make it even BETTER!

Yes, it is my final name for it. 
I had a long post explaining all the reasons but I'm sure it would bore everybody so I'll just give the basic reasoning. Most of us were already familier with classic 2GCDFIS, and the ATF/MMO treatment/trick. I put them together and viola! 2GCDFIS with transitor trick. (I didn't want to force everybody to memorise yet another acronym, nor did I want TT on the end of it because most people think of twin turbos when they see TT).
Then again, 2GCDFISw/TT doesn't look all that bad. It's just the addition of w/ for 'with' and TT for 'transistor trick'. Meh, most folks may not know what you're talking about. Besides, the transistor trick concept is still pretty young. Let's give it a while to let it sink into the general consciousness of the forum before we use this acronym.

Hey Ray,
if you are ever in the south bay, i can give you a ride in a 2nd w/ tt car, i don't know much about the msd though, so i don't know how they compare

I liked MSD and went with it...I'm very pleased with the end results. Smoother rev all the way to the red line and just looks sweet. I had to go with what the track guys use.

The reason you go direct fire with two coils when you get an MSD is so you don't burn out distributor caps and rotors all the time.
Seriously. The difference between MSD and a standard ignition setup (of which the FC ignition is a member) is like the difference between a standard ignition setup and a damp cardboard match in a rainstorm.

I did put them through a test.
My car would barely *run* in a zero-degree start. Pull the choke out all the way, and it would blubber around 800rpm and flood out if you didn't tend to the car.
After the MSD. Zero degrees overnight. Yank choke out, instant smooth 1500rpm, can safely ignore car and get out and brush snow/scrape ice/etc without having to be at the ready to jump into the car and keep the engine from flooding. Oh and 20% better fuel economy, too.
There *is* no comparison. A double ended coil is a hair better than stock, but the MSD literally blows them away.
If you're not using the MSD coils, by the way, you may not be getting the best results, either. Standard coils work with a capacitive discharge ignition, but for best results you need something with somewhat different characteristics.

But after that he is the one that started the thread which lead to the development with some help to make the 2GCDFIS with tranisistor trick I believe he has a lot of experiance with this and knows alot 2GCDFIS with tranisistor trick is a great up grade for your Rx for a fraction of the cost of the msd just check out this thread about the 2nd gen coil and you will see unless ypu have an extra $400+ to spend but this is just my opinion. https://www.rx7club.com/1st-generation-specific-1979-1985-18/transistor-trick-2gcdfis-411312/

I tried the MSD with two stock 1st gen (Diamond) coils. It was like blahsville. A little more power than stock cap and rotor. Then I tried DLIDFIS and low and behold it stopped backfiring! More fuel was actually burning. I didn't touch the carb through all of my early tests, and the mean temperature was around 50°F each time.
The MSD is worth it to some; I won't argue about that.
