My boss finally talked me into starting Star Trek. Which series do you recommend? I was thinking Voyager

The man i work is a 54 year old nerd/punk metalhead (i use those terms with endearmeant) who finally talked me into watching Star Trek. He actually recommend i DONT start with the original from like '65 and instead try another one. Voyager is the only one i know by name (deep space nine too i guess) so that was going to be my pick but put me on game with Star Trek! Which series is your favorite and why do you feel that way about it?
