My two cents, considering I am one of those newbs from the last few years:
I don't make .mod/xm because I suck at it, simple as that. Compared to LGPT/LSDJ, the pc trackers just seem clunky and scattered, it's too much for by spongey brain.
Kind of like what ant1 was saying, if I discovered trackers first, I would not necessarily have made my way to these forums. To come to think of it, I probably would have been like "wtf is this?" and turned back.
For some reason or another, I associate a certain style with tracker music (...Joule perhaps), though I am well aware of the wide variability. I feel that some of the best composers use pc sample trackers, but it almost never has the sound I'm looking for.
LSDJ is super streamlined and easy to understand, it takes like 10 minutes to learn. Jumping to piggy tracker is just as easy, and it has some very distinctive sounds that you won't likely hear anywhere else. Pretty much every command is self-explanatory (not hex digits), and I really like song->chain->phrase->table setup.
