For me, it's search. Search is absolutely terrible in every email client I've ever tried, except Google.

  Two observations: 1. Search was better in Opera 12 than in any email client I've ever used (Gmail included). That has never been surpassed. 2. Gmail used to have excellent search, until recently. Recently I've observed many very glaring bugs with it, where swathes of matching emails are completely omitted from search results. This is something that may have gone unnoticed if I'd not begun to use the search function to regularly recall emails I knew existed, but it's become a repeated, almost reliably testable phenomenon with my own account.
