Jenkins' French-and-Indian War figures still have a look that belie his origins as a sculptor of wargaming figures. Some of them look a little out of proportion, as many wargaming figures do. John's subsequent work has gotten increasingly better, better proportioned and well-finished. Frontline's are still very close to their origins as the inheritors of King-White/Reeves, sculpted and painted in what was known as "the Chinese Style". In any case, as was noted, those lines are all meant more for collectors rather than painters/modelers (though there is very good work being done, using such figures, making vignettes and dioramas, or repainting them. Have a look over at Treefrog Treasures toy soldier forum, if you've never been).
Prost!
