Weddingbee boards

Not really knowing much about these websites, I had signed up for an account both at WeddingChannel and TheKnot - but it seems that WeddingChannel is actually owned by TheKnot now, and while browsing through the content and tools, it seems like the sites are almost identical... I'm just wondering whether there are any differences between these websites so I can decide which site to use for my wedding planning (i.e. using the checklists, budgeters, guest lists, wedding websites, etc.).  What are the pros and cons of each website if any? What are your preferences and why? Or do you prefer some other wedding planning site like WeddingWire or MyWedding? There are too many options!

I used mywedding.com.  It had everything I wanted and was SUPER user friendly.  I also liked all of the different themes and options we could use.
