LC: Decision between SNGPT and SNGWIZ

[sence25]

Hi there, I know the FAQ, but I need some personal opinions.
I got SpadeICM right now, which I don't think is very comfortable, and would certainly not recommend.
I think it's time for either Wiz or PT.
Till I just talked to a friend of mine, I had almost decided to buy PT, because of the design of the program, the extra tools and because of its higher popularity in this forum.
But he just told me SNG Wiz can calculate overcalls, and I read some time ago about some option, which calculates future situations into decisions(like the good old 3-4bb utg with a trash hand thing).
Should that change my mind?
Thanks for any comments
