Cons
pinned.
needs big hole to pass through wood
deeper blade (typically)
more expensive
non pinned
can slip out the holders occasionally
bit fiddly to fit
pros, obverse of cons.
I'm not a heavy user by any means but I have this pack of blades that I'm still working my way through after a few years. they do a smaller 3 blade pack for 9 quid that would highlight which blades you use the most and then you can pick up those separately.
I do metal scroll work as well as wood, I have about a hundred blades for that which I got with the saw.
