Being born in the early 80's and growing up around all that music, it's the pick of the poll.
90's music was not too bad in stages, but it really took off imo around '98 when the unforgettable era of Trance really took shape. However, that goes from late 90's crossing over to the early 00's so cannot be defined to one era as such. Hard to decide, but the 80's wins the vote for me by a fine margin.
