They all have different usages, and neither are the better one because they are used in different fields. Therefore I can not answer you which program you should get.

I suggest you to read what you are buying before buying anything, because if you really have no idea what you want or need you are better of spending the money on ice-cream

You can read about the programs here:

I also suggest reading the rules before posting at this forum in the future, because tutorials is not the place to ask questions but to post tutorials clearly mentioned in the rules.

Have a nice day, if you have any questions regarding me closing this pm me.
