I think it all depends on the Clients Taste here. I mean zookbinders have that more traditional classic look to it where as Asuka Books has a newer more eclectic flair to it.
I found a link to asuka Books For you:

That should help you make a better informed Decision based apon the client and their personality.
Here is the link to zookbinders:

I cant find a link for Tyndall Photographic.
I honestly think it will ALL depend on the Personailty of the couple.
