Each DAW has his strenghts and weaknesses... It depends what want to compromise with. I've been out the production loop for a while now, but the programs I know about are Logic, Reason, Reaper, Cubase, Sonar, FL Studio, and I heard about Studio One and Digital Performer, but I think the main players are Logic, Reason and FL Studio (I think)
Like stated, the strenght of FL Studio is that it's super user friendly. You can get started making beats in seconds and learning the ins and out of beatmaking is super easy since it has a very visual interface. Also, when you purchase it, you get unlimited updates for life... But it's weakness is the the quality of the sounds. That being said, you can put some VSTs in there are that solves the problem, for me...
