Basically, what articles do you think best embody "doing it right" for some category where it's easy to go wrong (e.g. test logs, weapons, compulsions, memetics, disciplinary measures, cross-referencing)? Of course, there's going to be a lot of YMMV here, but that's part of the fun.
SCP-106 for something that can't really be contained, but damn if we aren't trying.
SCP-154 for weapons; it's neither too useful nor too deadly to the user.
SCP-170 for OTT; the test logs really make it, but…
SCP-241 takes the cake for test logs, IMHO.
SCP-668 both for compulsions and real-world tie-ins.
