Comparing two lenders' closing cost estimates: apples to apples?

[Brian Knox]

Two of my lenders sent their "closing cost" estimates for a loan amount of about $50k.

One guy seems to have included everything and the kitchen sink (termite inspection, entire year of home insurance, courier fee, etc). 

One guy seems to have left some things out.

In order to compare apples to apples, which portion of their estimates should I look at?

Just the "lending fees /origination fee / loan charge"? Or the APR?

In other words, if the prepaids and escrows and title searches are going to cost approximately the same regardless of lender, which portions can tell me which lender is a better deal?

Many thanks! Brian
