I just got a 0561. I was debating long before I got it. Was not all that excited about it.....that is until I opened the box and played with it. This thing is supreme in fit and finish. Likely the last folder ill ever need. Its that good, imho. Ergos are awesome, weight is lighter than I like for a knife this big, but I like heavy. For everyone else I imagine its perfect. Elmax I've played with for awhile in a spyderco mule. I'm a fan. Good steel.
Only thing other than the light weight I dont care for is the bearing pivot. Not cause it doesn't work, only cause I'm sloppy and slow on closing a folder and the bearings let the blade fall fast when using gravity. So I have to pay attention until I get used to it. I imagine most if not about all love it.
The lionspy would be my next choice, but on looks alone the 0560 gets my vote. I'm a spyderco guy. Started with them and own and carry and use more spydercos than any other brand, and I still picked the 0561.
Strider....ehhh. some love 'em. All I see is more money for less. I played with a couple....they didn't do it for me at their price point. Imo only the striders don't offer anymore than the other two choices. Ymmv.
Of course that's me and you are you. You got to carry and use it so take my comments for what they are worth......meaning not much.
