Sage Advanced vs Premium

SUGGESTED

We are planning to upgrade Standard to Premium based on the assumption that Premium is comparable (or not much slower than) to Advanced in terms of data input and reporting speed. Standard is very slow and painful to use, so our team needs better performance in terms of data input, research inquiry, and reporting  speed.  I've read that Advanced is a little but faster than Premium (especially for for data input), but have not seen for myself or not found any data (which sage took down) that shows how much of a difference there is.  Has anyone seen the difference for themselves?  Aside from the additional cost for SQL licenses, is there any other reason to upgrade to Advanced over Premium?   Thanks!
