I’ve never settled on a favorite myself, but I’m still hoping to find one.
My own taste is for “traditional” recipes that would have been the ones my grandmothers used but failed to hand down to me.
Other posters I’m sure will want sites with the latest variations.
I find myself using AllRecipes.com for “everyday” type meals. Most of the recipes have been well reviewed by other users and I usually find their comments to be very helpful.
I’m a big fan of www.recipezaar.com it has great filters for getting to the stuff you really want.

I use Google, honestly. Just type in the name of whatever recipe I’m looking for. I usually find something I’m happy with in the first two pages of results.
If I have something very generic to look for (“chicken recipes”) then I go to AllRecipes. I also like Cooks.com.
I used to use cooks.com but they have like 2,000 versions for every recipe that’s even remotely popular. I like being able to filter results, or “sift” them as recipezaar.com calls it.
Ditto. I also like their Meal Planning and Shopping List features. In fact, I recently paid for the Premium membership (I was satisfied with Free for three years or so) so that I can add my own items to the Shopping List (“cat litter, baby wipes, small light bulbs”) and so that I can instantly post a new recipe to my private folder, instead of waiting overnight to get it “published” so I can get the nutritional information on it.
Epicurious has recipes for nearly anything, with many coming from good pubs like Bon Appetit.
The Old Farmers Almanac has great recipes, especially for baking.
How many recipes have you published there? I’ve only put up two of my own, and one of them is so simple that it almost doesn’t qualify as a recipe.
Like** flickster** here I really like www.allrecipes.com As said, you can get useful recipe comments. The site will also change the number of servings for you, or switch recipe measurements to metric if you prefer that. Recipes also come with fairly complete nutritional information.
If you want to search for a particular recipe there are several helpful search functions. Say you have a lot of chicken and cheese and onions on hand, but hate celery or mushrooms, you can use the ingredient search for recipes that use what you have but exclude what you don’t like.
It really is my favorite site, the one I go to first, but I like several others mentioned here as well.
I’ve put up 11 for public reading, although to be honest, most of them aren’t “mine” either. That’s the other thing I like about Recipezaar - I can post things from Weight Watchers and other sources pretty easily, with just a few tweaks of formatting. It’s nice having one spot for everything, and again, so nice with the Shopping List Feature - not only can I just click on my meals for the week and get a shopping list, but I can edit the shopping list (“No, we don’t need to buy salt, I’ve already got that!”) and it shows both the amount of the ingredient you need for each recipe (“Tomatoes, one whole, 1/2 cup chopped, 1/4 cup diced” - ETA Which, now that I think about it, would be fantastic for OAMC, if I could get my act in gear to do that!) and also tells me WHICH recipe each ingredient is required for. So if I get to the market and asparagus is $5 a pound, I can look at my shopping list and see why I wanted it and decide on a good substitute (“Spring Vegetable Strata…hmm…green beans would work in that, let me see how much those are.”)
I’ve started spending a whole lot less at the supermarket since using their Shopping List, especially now that I can add my things to it. It works so much better than keeping a “list” in my brain ever did! 
That’s what I was going to say. Moreover if you go to (advanced) search you can search in dozens of different way. Including be season, by meal course, by ethnic orgin, by specific ingredient…etc. Plus, you get feedback from people who have made it. Like “This sucks, don’t bother”, or “This was great, but instead of A I did B”. Very helpful.
Whoa. I use that site and have wished for that very function; I didn’t realize they already had it!
I use Food Network.com, but I’m addicted to that cahnnel. I also use Allrecipes a lot, as well as Kraft. With Kraft though, I usually just get ideas for ingredient combos, and look for other recipes like their’s, then make up my own recipe. Kraft can be very bland. I did get a great hint from them, though - when you have to saute something like chicken chunks, use a vinegraitte type bottled dressing instead of plain olive oil. Lots of flavor!
Another vote for Epicurious. I also like recipes from the Food Network. Reader feedback is a must (though I hate it when people change the entire recipe, especially to fit their diet restrictions, then ‘rate’ it anyway)
