I agree with what you've written so much, that I actually had to scroll back up to check I hadn't written it myself when I got in from the pub last night and just couldn't remember doing it!
Personally I am not overly influenced by "payment model" in terms of having to make a choice, and I am not interested in anything being a "WoW killer", however I do not have enough time to play both GW2 and WoW and be able to do either one of them justice - and so without revealing which game I am more in favour of, I will simply pick one of them and cancel my subscription to the other. *cough* *cough*
