Well I also advice you to stay with HostGator as they are far better then 000webhost and also HostGator is reliable hosting service provider!
What do you think to try RV89? https://www.rv89.eu/uk/Hosting/Linux/ Is a very good service, HostGrator and 000Webhost don't let you see the server load.. they hide many things.. RV89 let you see all the load, that is the different for the seriusly of a company. http://www.rv89.eu/uk/Monitor-Serivice-Statistics/WebHosting/
Lol in order to pay the $4.84/mo at hosting24.com (the paid service of 000webhost) you have to pay for the next 36 months. If your billing cycle is monthly, then you'd have to pay $7.84, saving only 11 cents. Does it worth it? Stay with hostgator. They eat up the competition lol
I dont know about 000webhosts paid hosting but I used their free hosting for years and didnt had any downtime!
