I always have used the "modern" comparison operators like >= or <= instead of the "archaic" ones like GE or LE as well just because I like them better.

However, for humans my manager maintained that multiple studies have shown our human brains make less mistakes when using the "archaic" ones, e.g., GE, LE etc.

I do not care one way nor the other, however IMO it should be consistent within that program. IOW, if I have to maintain a program I use the what was used unless it is easy to change the GE to >= etc. throughout the program. If it is already mixed up and not easily changeable I use my way.

To me, one style is neither archaic nor modern, just different. E.g., IBM's VM/Rexx (very nice) language has been using =>, <> etc. since the early 1980s so does that make it "modern"?
