Not really sure what features you're looking for. Between those two (I have both) I think I prefer the Strobe simply for the opening. It opens practically instantly with the KVT bearings. It has kind of a strong detent which works against it when closing it, careful not to cut your thumb. It's easier to close if you push the frame open far enough to clear the detent ball, but that takes more effort. But they're both good knives. I love the design of the Skyline with the thumbstud blade stops and light weight. Makes it both light as well as strong as possible, being so thin. The design of the Strobe is uglier and the black scale sticks out weird, having a gap against the frame lock when open. They're pretty similar overall both with pros and cons. The Strobe has a little thicker blade and thicker frame, being an entire steel frame, not just liners. But it also weighs more. Strobe's pocket clip has a pretty weird connection but it's deep-carry. It's right/left tip-up only. Skyline is right-only but tip-up or tip-down. Skyline also has a lanyard hole. Strobe's scales are plastic-y and rounder, Skyline is textured G10 and flatter. Skyline's a hollow grind, Strobe is a flat grind. They're both about the same length, but Strobe is the longer one on both blade and overall (less than a 1/5th of an inch). Strobe is the funner and faster to flip, Skyline has a pretty crappy manual flip but can still be opened well if you do it right (have to manually create a stronger detent/initial force with your finger, so kinda rest it on there and then push/flick quickly maybe with a follow through? heh, I dunno, but it's definitely possible to open it fast without flicking your wrist).
All in all, not sure, they're both good. I prefer each for different reasons. The Skyline is a little lighter and flimsier-feeling, but might be a better design and a better carry. The Strobe seems a little stronger and has the easier, faster opening but might be weirder or not look as good to you. I might choose the Strobe as the winner but that's mainly because I also have the BladeHQ-exclusive Skylines with S30V+carbon fiber, so I'd choose those over both, heh.
And there's other cheaper Kershaws you could consider. The Starter if you don't mind it's heavy weight or looks. Or the Volt SS, thinner, dressier. Or the Scrambler. I highly recommend any of those three, but unlike the Strobe & Skyline, they all have SpeedSafe assisted opening, not sure if you want that (easier to open, harder to close).
