I agree, the astrological software field is highly competitive. I don't use the interpretative features of my software (Winstar Plus) so I haven't a clue if it's any good. IT comes with about 300 charts and tons of features, (various synastry charts, relocation charts, progressions, returns, transit searches, etc....probably all the professional level software has this.)
The nice thing about having a program like this is the ease of creating so many charts and instead of getting caught up in the math, having a lot more time to study the charts themselves. My math skills are decent, but I always worry about mistakes, and my software gives me confidence that I'm looking at the right chart (we all know that software doesn't make mistakes!)
Thanks for posting this. I have no intentions of switching, but am always curious what's out there, what people use.
