Manual transmissions are not very demanding for lubrication. ATF works well in most but what is the point of the clutch additives if you don't have clutch material. ATF is the thinnest generally available automotive fluid and that is the main requirement for low drag in a transmission that uses splash oiling.
I am using the thinnest Red Line MTL, which is 70W-80. It is a thin gear oil specifically formulated for manual transmissions. It is a little bit thicker than ATF. Works for me.
Honda specifies MTF, MTF3 is the actual mixture. But it also works with MTF or MTF2. Do NOT use anything else like engine oil, ATF or the like if your gearbox is still working ok.
Its still working OK but with a little stickieness in the synchronizers when cold. So, I think I will try using ATF for a few days and then drain and fill with MTF so that I can flush out any crap that has built up. I will be using it in light duty for those three days and let the lighter ATF flush it out before putting in the proper stuff that is a bit heavier.

I also have the 1st and 2nd gear grind issue. Currently I use Amsoil synchromesh. I cant tell if it improved, but it seems fine, definitely still grinds when going into first above 5mph, and also when going into 2nd from 3rd if speeds are above 20mph.

User manual says if Honda MTF is not available, SAE 10w-30 or 10w-40 may be used, but just temporarily.
That's just because engine oil is better than no oil at all.
MTF smells quite different than any engine oil because of the different additive combination. The oil in the gearbox doesn't has to sustain high temperature or oxidation like the engine oil in the engine BUT it has to cope with high pressure of the gears.
I have noticed over the years that tranny oil and diff oil have a very distinctive smell, almost like sulfur. But I would think that sulfur would be a bad thing in an oil that gets high pressure squeezing as it would melt.

If you're thinking about sulfur melting, you seem to have elemental sulfur in mind. I'm not sure why elemental sulfur would be in MTF, and in any case it would not cause a smell because elemental sulfur is nearly odorless. The smelly sulfur compounds are H2S (hydrogen sulfide, a gas, rotten egg smell) and various organic thiols (having an -SH group somewhere, incredibly awful smells), and I don't know why they would be in MTF.
MTF (and hypoid oils) do have a very distinctive smell but it doesn't smell like a sulfur compound to me. Possibly some sort of aromatic hydrocarbon compound???
