I hardly ever see Duracell - generally only when there are batteries included in something, for example Microsoft keyboards and mice. I've found Dick Smith branded AA batteries to be quite good, and very cheap, but I
won't be buying them any more now 
For AAA and 9V I've been using "Maxlife" - a brand I get from one of the IT distributors I use - but I don't really use enough to know if they're any good. The 9V ones seem to last ok in smoke alarms. For CR2032 and other button cells I'll generally buy from wherever is cheapest - the last CR2032's I got were off eBay, and I'm waiting on some Maxlife LR43's for a new stylus gauge thingy that just arrived (the gauge itself came from Aliexpress).
