VPS which is good for hosting a heavy web site

[JissyKarter]

VPS accounts from hostingsource.com and libertyvps.net are attractive for me and I am in two minds which way is better to follow? What would you do being in my place?

Understand Your Needs – Determine whether you need shared, VPS, dedicated, or cloud hosting based on your website’s traffic and functionality.
Choosing the right type ensures optimal performance and cost-effectiveness.

I've been using hostingsource.com for about 8 months. I run my site at their personal hosting plans. I host audio, video, sign ups, etc. I could not be happier!
The features included in them are really cool: Unlimited Features, Site Transfer, PHP, MySQL, CPanel, Site Builder. My sites have run fast and the cost is amazing.
