Look, if you are pushing me for an choice, I would do the following :
Logic !
You have enough to go on in the previous replies to convince you ... but remember, that with any DAW or sequencer you have a learning curve and some are more intuitive than others .... I have used all of those you list ( I use Cubase, Nuendo and Reason of choice ), but I have always said that I would like Apple to release Logic 10 cross-platfrom, as I refuse to go Mac only to get it. I used Logic up to 5 Platinum, and also use Pro 9 in a local studio and I absolutely love the plugs and virtuals that come with it - top quality stuff all around. The sampler in logic is also great, but does take a little getting used to ... but once done, it is a little gem. For the money, the features and the quality alone, it would be Logic all the way for me ...
Happy choosing ?
Give a little more, expect a little less ... but always put number 1 first !
Live life and do your best to make it fit around you in a loving and productive way ....
