I ride a specialized sequoia elite, which from the photos looks pretty similar to the sirrus except with drop bars. I love the bike. great ride, super-comfortable and fast once i fix the motor. The only things i don't like about it are no front rack mounts (not a big deal yet, i could always buy a steel touring fork), and little clearance for fenders. The sirrus looks like it's got V brakes so the clearance wouldn't be as much of an issue it doesn't look like.

also look at the novarra big buzz. I've never ridden one, but it looks similar to the other bikes you've posted and I've heard good things about them.
