You know, I haven't watched a lot of Voyager since it went off the air, but I don't remember their treatment of the Borg being all that bad. The parts that I remember, I pretty much liked.
You could actually say that that despite obvious advancements made in fighting the Borg, that Voyager made the Borg more formidable than ever....I mean tactical cubes, diamond ships, a huge space station complex (unimatrix zero), and after the defeat of Species 8472, nothing could really stand against the Borg in the long run.
