Advice Needed!

I need some advice from all of you pros out there. My office is currently looking for a live imaging package for backups on our servers (we are eventually looking to virtualize a few of them to help limit downtime). I am currently looking at either Symantec Live State Recovery or the Acronis True Image Server for Windows. Do any of you have any feedback on which you prefer?

Or is there another option out there that I am missing?

Thanks for any help you can give me.
