Turns out that was nonsense. The difference in effort is extreme, the MFFG is for sure annoying and somewhat painful to use, where as the SLX ate the nug like it was nothing!
It took 3 goes to process the herb in the first shot through the MFFG, the SLX had twice the product and took all of 10-20s.
I was MFFGing for minutes and my wrists got sore lol
Also, the MFFG is filthy now, where as the SLX looks identical to pre-grind.
Using the same 4 weeks-since-harvest Chocolate Kush, I thought I'd show the particulate size difference between an SLX and a MFFG.
MFFG Set up:
It fits on a small 420 science concentrates jar, not perfectly, but it does help grip the base.
It stores the herb perfectly in it (airtight), and is reasonable to dispense from too.

Each black square in the silicone mat is 1mm

Look at that fluff in the jar though, gorgeous. It's extremely finely and consistently separated.
A little bit of pain is worth it to get some exclusive pixie dust.
Sure, not every vape out there can deal with this fine a grind, but there are plenty that can. And when they can, they will extract the goodies, and a better off-gas spectrum, faster from the finer grind generally.
edit: After vaping a couple of chambers from either grinder, I'd say the vapour is different and not truly better in either one, though there are advantages to either.
The SLX may have given better flavour, or at least it was a lighter vapour and more enjoyable in that sense.
The MFFG causes it to cloud up a little faster and gets super dense, it then fades faster than the coarser grind giving fewer hits of any toke style. It hit me so hard I forgot to try and taste the cocoa vibes of this strain.
I would say it was more intense, which is why I said better earlier. But really, it's just different. I'll be making the effort to use the MFFG more now though, it's like a mid-way to kief power hit, and it's great having a jar of it on hand
