The ones I like are 1 and 3 the best.
2 I dislike because of the spamming and immature attitude. Sure they might get better, but they might get worse or not change either. Their too new still so I think more time to let them be on the forums is needed.
4 I wouldn't mind on staff, they seem like they will do a good job, but already looking at our group I think they will probably just be a rehash of what we already have covered well.
5 I already said I disliked because they were non-confrontational, which I feel a mod of any forums needs to be ready to handle. Sometimes closing a members thread for spam won't go over well. Remember that 'ATTN: AZAR!' junk for not that long ago? Closing over and over won't fix the problem, eventually you just have to talk to the person and let them know what they did wrong and why moderative action was taken.
