The only Star Trek my brother likes is VOY, my son's best-friends Mother, her ex and new partner all like VOY the best (the DVDs were part of the divorce settlement). My husbands friends wife loves Janeway, the young girl who works in the bookshop tells me she loves VOY. Some of them also like DS9.
The guys I know who like TNG are older. No-one I know (not through a board) likes TOS the best.):
