I have the Marksman but not the Vantage, though I have handled a couple of them.
I have an acute bias against liner locks which admittedly, skews my opinion towards anything I don't have to put my fingers in the path of the blade to close. Even my CSART has been assigned to glove box duty which is a shame since it's a fine tough duty knife.
That being said, the Marksman has replaced all other knives in my collection for daily carry/use. It's light, tough, quick to open and close, feels great in hand, etc.. The clip is tough on pockets though. My remedy was simply a length of 550 cord through the clip that works as a buffer between the clip and the edge of the pocket.
One thing I'm struggling with though is sharpening the blade. I think I'm making it too sharp and keen because I feel like I'm touching it up too often. Maybe ill stop at 600 grit and see if that will help. But that's an entirely new discussion to have some time.
