1) ENT 2) TOS 3) DS9 4) TNG 6) VOY [7) DSC] I love "Enterprise", it's my favorite Star Trek series since 2001 and so the sole lead. I tend to team up TOS and TAS in such rankings. TAS alone is a bit hard zu compate to all the other live action series. DS9 on third place is quiet close to TOS. TNG and VOY are close too. Ranking DSC on 7 should not be overrated. For me the new series is quiet strange. I am not able to put the series into context and I don't see what it aims for. But that can definity change with more episodes.
