I have several Sebenzas in both styles, large and small. They're all great. In the small size, I prefer the classic. In the large size, I use a regular more often for "day to day" kinds of use (I have one in my pocket as I type this), but I use a classic for hiking and camping, because I find the pointier blade a little more versatile.
If you can, get both. Whatever your choice, I would suggest getting dual thumblugs for your Sebenza, since a single thumblug is standard (which is one of my very few gripes about the Sebenza).
