SMAC vs SMACX

[TheSmitty]

Since I now have both SMAC and SMACX and they are both the latest versions I was wondering....
Which one should I play? Is the AI comparable between the two? Is one more solid than the other? Even if I want to play with the original 7 factions which version should I use?

Sorry for the questions but I am sure the seasoned people here have some opinions.

Thanks

Well, I may be lazy, but I would just start with Smacx, and play the origional 7 factions at first. Starting with Smacx, you don't have to unlearn anything, and the games are so similar that IMHO you won't lose anything by never playing 'classic' Smac. Playing the original factions simplifies the game somewhat (no aliens), and many discussions exist on this site regarding the characteristics and strategies of the first 7 factions. Once you get a handle on the game, you can expand your horizons, adding complexity as you are ready.
