None. GoDaddy is horrible and BlueHost and HostGator are owned by EIG which is a horrible company that buys hosting companies just to fire all of the employees and use their support services which suck. EW.
All of them are extremely popular but I would say GoDaddy is the most popular. Still I dont have the biggest experience here so would be cool if some experts say their thoughts on this.
HostGator and GoDaddy provides dedicated hosting and VPS. They are wonderful hosting company but when it comes to price and affordability. Goddady is more affordable comparing the economic plan of $1/month to hostgator hatching plan of $3.48/month
