I own about a dozen Sebenzas and a wide selection of Strider's.
I have carried them all and used them.
The Sebenza actually has a very thick edge. I was SHOCKED when I took some calipers to actually measure how thick they are. The hollow grind and pretty lines of the knife make it seem more refined and delicate than it is.
I like the Sebenzas well enough. Down sides are in my opinion they do not harden the S30V enough. While good they do not seem to stay sharp as long as my SMFs for instance. The Sebenza is a very nice looking and wonderfully consistent knife.
Which brings me to the SMF. The flat ground blade is no thicker at the edge than a Sebenza and Like the Sebenza can benefit from some thinning. I find once this is done the Strider with its flat grind out cuts the Sebenza.
Here is a picture of two SMF blades one with the factory edge and one I thinned and convexed.
I generally carry a SMF. For me its the perfect folder. Sized just right. Rides deep in the pocket. Very secure in the hand. Great Lock up. I am pretty sure the Strider specification for the heat treatment of the S30V is better. The blades sharpen and polish really well and seem to hold the edge longer.
I do have a military back ground and much of what I think about knives and weapons in general have been influenced by that experiance. I like the way Striders look.
Be your own man here and make up your own mind after holding them and checking them out. Its popular and trendy to bad mouth Strider right now on this Forum. Take all that with a grain of salt. Most people on this Forum don't even use their knives.
You can't go wrong with either knife! BUY WHAT YOU WANT!!
