placed an order for some snuff suede chukkas.
jt, to answer your question and after re-reading your post in a non-bourbon induced state of mind there are differences in both, obvi. your wording made it sound like a lot of people prefer the suede chukkas over the #8 shells. imo, i prefer #8, but both have their place.
Last - suede is typically on the Leydon and the #8 is typically on the Barrie. all depends on your foot. some guys fit in others better, but i don't have that problem.
Sole - Suedes typically have single leather, #8 typically comes in double leather. you can feel the difference, but comfort is the same for me. i have not seen suedes in a commando sole, but #8s sometimes get made up with them. Commando is a really nice sole.
Lining - unlined or lined. doesn't matter to me. unlined may be a little more comfy, but that is debatable since both are comfy.
both serve different purposes for me. IMO, if you can only get one, i'd go with #8 shell, that is if you can spare the extra $$$. i think #8 is bit more versatile, but that's just my opinion and personal taste.
