[Star Trek] How much individuality does each Borg have?

Been catching up on some adventures of the starships Enterprise-D and Voyager. How much individual volition or sense of self does any one Borg have? They always say "We are Borg" rather than "I am Borg" which I found interesting. 

I just saw 7 of 9's introduction on Voyager, but I don't mind spoilers (although other readers may appreciate a spoiler warning).

Borg have very little individuality.   They refer to their own body as a number of a group when separate (physically) from the collective.  Geordie and Data did teach one borg, "Hue" individuality and this practically crippled the borg once the concept was introduced to the collective.

The hivemind that the borg are sees itself as individually parts of one mind. So "we (separate bodies) are (one with the hivemind that is) borg." This really isn't dissimilar from animals like certain species of ants or bees.

Anyway there is a bit more interesting philosophical ideas about the borg. They have... wait... hold on... what is that...
