I feel like GoDaddy's domain appraisal tool is better than Estibot. Estibot looks at searches of a domains words together, but I think it doesn't take into account the value of the keywords individually. I know GoDaddy's tool is free and Estibot costs money after a few appraisals, but that doesn't automatically make it better. I think it makes sense for GoDaddy to separate the words and recognize their value individually. Also I think NameBio has better comparable sales than Estibot. It seems like Estibot finds the worst comparable sales it can for a domain compared to GoDaddy and NameBio. GoDaddy's comparable sales are more average. What do you think?
