If you have decided to jump ship from iWork due to the large list of removed functionality, what program are you going to?

Before anybody says it, I understand that Pages '09 still exists in my computer and that Pages 5.0 did not overwrite it. However I find it frustrating to have to open 2 different instances of virtually the same program to perform basic word processing tasks (the largest of which being a mail merge). Big question being "What office suite or word processor is the one to switch to?" I don't mind spending money on a good word processor or office suite, so long as it lives up to its price tag. Anybody have any recommendations?
