Which site do you find easier for guests to RSVP? I'm planning on having everyone RSVP online and also include my phone number on the invite saying you can also call/text me. I haven't created a website on either yet because I can't decide between them! Both seem easy enough to create and navigate. I've had troubles with the Knot while trying to RSVP to other people's weddings because it seems like you can either type in your name to add to the list or type it in to find your invite, depending on if the couple added everyone's names in... maybe I'm crazy but it's been difficult to figure out. I assume they're both easy to shop the registry's through.
