For me, my favorite is Auxey-Duresses (red). I'm also highly partial to Chateauneuf-du-Pape and Gigondas. For white, I'd say my preferred one now is from Alsace, specifically probably a Tokay Pinot Gris. I prefer French wine simply because I know it much better than anything else.
For Chianti, I highly recommend the Ruffino Chianti Classico which comes with a gold foil label. That's the best one I've ever had, somewhere around $30/bottle. I can't get it here, but I had it a few times in the States several years ago.
