I worked with STL some but am much more familiar with structured text as used by Rockwell/Allen-Bradley. However, my first exposure to PLCs after getting out of the Navy back in 1991 was the Mitsubishi A series with a GPP for a programmer. I found that one interesting because you could program in ladder mode or switch to the other mode (which I can't remember the name of) that looked exactly like assembly. The two modes were interchangeable as far as I could tell.
