Striders aren't "refined." They were developed as a tool for rough use in the field, by soldiers, who often wear gloves because the environment and equipment are harsher than normal life. Hence the exaggerated grooves on the back of the handle and a more overbuilt tone to the knife.
Sebenzas are "refined," in a manner that would go along with everyday use of a fine knife for little personal chores. They have nice lines with a restrained aesthetic, and the kit that comes along with them in the way of a bag, box, and certificate of authenticity (birth certificate with born on date,) lends itself to satisfying inner satisfactions.
That does not by any means say that one can't do the job of the other, considering they are just modern folders. But they are marketed to two different groups, in different publications. They have different shapes and blade grinds, too, to enhance different cutting tasks. About the only similarity they have is the price, an S30V blade, and titanium scales.
You can cut Cuban cigars with a SnG, or dig a firing port out of an adobe wall with the Sebenza, but those chores aren't quite what the respective makers have oriented their product to do. What needs to be decided is what each knife offers to the buyer and how it fills his needs to get one. They are not the same knife, the looks aren't too subtly similar to see a difference. The decision the average SnG vs Sebenza knife buyer is really asking is which crowd do I want to impress by owning one, and what does it say about me?
We can't answer that. Make a choice, it's up to you and you alone. Either way you will get an outstanding knife, but what you derive from owning it is largely subjective to your criteria alone, and nobody can decide it for you in advance. You pays your money and takes a chance.
