I much prefer processing my own brass. Most of my LC is range pickup but I did buy 1k of 5.56 once that was mostly LC.
I have opened up the primer pockets by both chamfering with the Hornady tool or a countersink tool in a drill, or swageing with the Dillon tool. Honestly I have seen no difference in the end result and chamfering is much faster.
If you don't have the tools required, or several hours available to process the brass or you don't really enjoy spending the time required, buy the processed stuff.
Either way, LC brass is some of the best.
