I'm sure it varies from person to person, but I find it very frustrating to use Chrome's equivalent of the "Awesome Bar" when I'm forced to (eg work computer); Firefox just seems to do a much better job of surfacing open tabs (yes, I'm a tab hoarder), bookmarks, history, etc while Chrome seems like it'll surface some dubiously relevant options and try to railroad you into search. Even when I know I have a tab open and I know the domain name or a substantial chunk of the title it is legitimately rare for Chrome to offer to switch me to that tab, and often times it will surface one or two tabs that seem utterly unrelated. Bafflingly bad performance from what used to be a search company.
