I started to use Pan X in the last couple years it was out, but the first couple times was for copy work. It does have larger grain than TMX. I should scan up my college films on TMX and see if it shows any qualities I like, now that I can scan them instead of print them. I certainly didn't warm to it then.
I decided to get another 35mm roll of TMAX 100, so I can shoot it with some Pan X in the same. Do another test of it. Maybe a follow-up video from my first one. Its true I haven't warmed to TMX over the times I've used it, but its probably because I didn't shoot enough of it.
Andy's video certainly shows the two films are indeed similar in look, which is what I got as well. Its just the grain I dont like as much. I also had found Pan X had a glow to it on some tones, which I never noticed much with TMX. Except one shot I did, which was the only shot to me which showed what TMX actually could do. Its the only shot on TMX I liked enough. Here it is:
