Next step selecting an alternate programming language

Ok it's down to ADA or Object Pascal (the Free Pascal compiler). I still have to check the license for FP in more details but it looks good. Two languages that have compilers on several platform and libraries to go along. I have worked with Turbo Pascal and Delphi years ago and the Free Pascal version of the language is a very close clone of Delphi so the learning curve should not be too bad. I have played a little with ADA and so far I think the language has very interesting features. I might actually start a more detailed thread about my ADA experimentations. What do you think ? Does anyone out there have any comments about either language ?
