Both restaurants are essentially the same as far as food quality. The Melting Pot is a bit more trendy and I feel like I need to dress up more there. Simply Fondue is still very nice and has a great atmosphere, but I see people a little more laid back there. Melting Pot also tends to be more difficult to get into at the last minute. Definitely call ahead if you go there. Simply Fondue, on the other hand has always had openings anytime we wanted to go even last minute I very rarely see children there, especially young ones. Neither are places that really cater to kids. I did see a toddler there last week, but personally I would never take a child under 10 or so to either. Of course, I am sure they wouldn't turn you away. Good luck. I love fondue :)
