This is a silly question because there is no definitive answer.
If every question on this forum was answered by typing "Just try it and see" the forum wouldn't really have much room for discussion.
Discussions are great and Im all for it. But instead of trying to reinvent the wheel and asking the same question that was asked before, why not just read the previous thread as slick salmon points out. There must be something else to ask about HDR software instead of which is best. And yes you do ask which is best, because no one is going to recommend the worst one. And no one will admit they paid for and are using the worst one. Software is more than which gives the best results. Some are intuitive and some are not. How you adapt to it is important so thats why I suggested you use the trials and decide for yourself which is the best one for you. Its not necessarily the best one for everyone. I agree with Light Guru a lot of the times, but I still try out more than one software to see which gives me the results I want. And I agree with Light Guru all the time regarding B&W. Nothing beats Silver Effex Pro. Also as a newbie here you are doing both yourself and the site an injustice by not browsing through the previous threads which are here for just that purpose and will actually answer a lot of your questions. Now a new question, that would be nice.
