It sounds as if you haven't seen either VOY or ENT, so really the only way to find out if you like them is it watch them. Both shows have their fans and their detractors and those people inbetween who feel that there was plenty of missed opportunites to make them better.
Yeah, really just netflix a couple episodes of both shows and decide for yourself if you like it enough to continue.
Personally, I like ALL the series, and they all have their highs and lows. Form your own opinion on them.
