Kaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahn!

What I meant by Voyager being dumbed down was in relation to the characters and actual storylines; whilst you're right that they actually upped the technobabble, they ditched any actual overtures towards something deeper than popcorn television. Technobabble just excused bad Deus ex Machina. As for the Borg, just like in Enterprise, they were solely written in to try and save the series from going kaput. Whilst it managed to prolong Voyager's life for a good few series, it did next to nothing for Enterprise, especially since fans were still narked over Voyager.
