Media temple vs Host Gator for ecommerce

I want to host an e-commerce site which will obviously have SSL Certs & Dedicated IP.

I have recently come across Host Gator & Media temple.

HostGator’s Business Plan that includes Private SSL Cert & IP $12.95/mo
vs
Media Temple Grid Service $20/mo

Here’s my current Site Statistic’s /mo
Unique Visitor - 1081
Number Of Visits - 1611
Pages - 20144
Hits - 139474
Bandwith - 2.72 GB

The above staticts are the site without e-commerce, so when e-commerce is integrated they are bound to increase.
Using Joomla for the site.

Money Not an Issue. Looking for excellent quality host & high speed

I thin you should stick to Hostgator. IT will facilitate you according to your changing needs. It works fine for me.
