Ah, ok, I thought you were literally talking about the looks ("good looking alternative")...
True, if one wants have the guarantee of certainly no "Seki lockrock" the comp.lock would do that.
Stronger though?
I am not aware of any data that would support this. I feel (no data too, to be clear) that a backlock is at least as strong. Supported perhaps a bit by Sal and Eric saying that on really large folders like the Police they like a backlock particularly for its exceptional strength.
Not a thing anyway, both more than strong enough (multiple times I guess), but saying with certainty that one is stronger than the other is nothing I could do.
I personally am glad that this great model has a backlock. For me better ergos (no cutout, closed back), better usability with gloves and imo the most versatile.
But: If they made an additional CL version of this great knife: Just fine!
