I've gotta admit, I was absolutely PUMPED for Rift (and still am :D) but GW2 really caught my eye as something I will almost certainly enjoy for a long time.
I was genuinely worried for a second that i wouldn't be able to spend any non-beta game time with the awesome people here at Gaiscioch (Rift will be a subscription game [or so I've heard] and I'm a little too poor to afford that) but the payment method for GW2 is what I like most. Just a one-time purchase, no subscription!
So even though I won't be able to play any Rift once it releases (unless the subscription is really cheap) I'm quite excitedly looking forward to playing lotsa GW2 with the 'Cioch whenever it releases.
I learned something about myself just now...I tend to use a lot of parentheticals. :D
