Unfortunately astrological signs didn't give me any 'opposites' I can compare myself with. Having read through the descriptions of various character types associated with various astrological signs, I cannot say I identify with one any more than another.

MB-types give me a set of sliding scales. I show up as strongly I and strongly N, which allows me to compare myself with ES types - I recognise very little of myself in ES types, and a lot more of myself in IN types, which means I'm biased towards the assumption that there is at least some basis to it.

I can also make predictions about what types my friends are, and (before telling them my guess) ask them what type they are. Currently these predictions seem to be matching up pretty well, although a little fuzzy on the P/J axis.

I don't know much astrology so I'm not able to address that issue, but decades ago I studied handwriting analysis. I realized there were "opposites", but they were always described in a positive manner. For example, long endings on a script 'e' were associated with generous people. The opposite, a short 'e' ending, would be associated with a thrifty individual -- as opposed to the more blunt cheapskate.

Maybe that's just wordsmithing but it seems reasonable to characterize attributes in a positive way.
