Pinned-Not for the faint of heart to install, you only have one chance to get it right-more of a permanent install-You need an accurate method to precisely drill the block/barrel-you need taper reamers and need to know how to use them which most DIYers dont.-usually lighter. One less thing to worry about falling off.
They both have their place in the world. If you are the type that changes front ends or think your rifle is an erector set and want to try a bunch of different set ups or take it apart then the bolt on has merit.
I prefer the pinned style myself-once it is correctly installed you typically dont ever have to worry about it.
