I like sixths rangers because they shake up the status quo. Maybe not as much any more, since they tend to get introduced early and just become an official team member, but if you go back to their introduction...Burai's story was a HUGE part of Zyuranger. The rivalry between him and Geki, his relationship with Bandora...he wasn't just another team member, and he wasn't just another villain. Abarekiller is another good example. So that's why I like 6th rangers - they have the potential for good storytelling, they shake up the standard team dynamic, and are just a nice change of pace sometimes.
