Webmail Security

I currently have both a Gmail and a Hotmail / Windows Live account.  While I know nothing is 100% foolproof, I'm trying to decide which one I want to consolidate to, and its driving me nuts.  A year ago, the natural choice was Gmail IMHO.  However, Microsoft has made a LOT of improvements to Hotmail.  Gmail has two-factor authentication for added security (but a lot of apps require locked-in passwords to be created anyway to bypass two factor).  Hotmail has single-use passwords.

 

From a security standpoint, is there much of a difference between the two?  I know Hotmail now claims it is fully https from the browser to the email server - Is Gmail the same?
