This is almost impossible to answer.
Some seem to bite better than others but that is usually the result of them being in great numbers.
I've fished inside a school of sockeye and we could not find jigs that would NOT catch them.
Pinks as well can be watched chasing a lure or jig in large groups.
But then you have Chinooks, who when are on the bite will absolutely annihilate a large lure or huge glob of eggs. If you have never witnessed a Chinook take down a Kwikfish while backtrolling, then your missing something impressive :thumbup:.
Coho as well can be super aggressive, charging across pools to crush spinning metal.
They are all good biters given certain circumstances, it's in their nature to hunt their food and this is what makes them the kings of the sportfishing world.
I might add that the most aggressive of all is not really a salmon, but the good old steelhead, I've heard of 5 rods popping their clips in the great lakes when finding a school of steelhead.
At least when the last steelhead are being netted off the BC coast, the Steelhead will still be catchable.
