I'm a big fan of their free e-mail forwarding and customer support (they got a domain back for me that I had let expire out of its grace period).
But, I'm surprised so many people tolerated godaddy for this long just because of their control panel. Every time I have to go in there and help a client/friend, I begin to feel like an idiot almost immediately. It's impossible to find anything intuitively and I feel like their design changes every few months.
Namecheaps panel isn't pretty by a long shot, but it's so clutter free I just don't care.
