I did not post the reason(s) why members in my squadron are suggesting these services.We have used Google Aps. However the member suggesting these services stated that using them will look more professional with a .org domain besides getting more advantages such as a lot of themes to chose from.
I used to be a reseller for Hostgator and left them because of constant server issues and unreliability.
OP did not specify if he needs a host for a CAP site(?) Maybe he has a side business.
