There are a few things I like IKEA for (the aforementioned "Grundtal" kitchen racks work really well) but generally I prefer more individual furniture (watch Friends where Phoebe responds to Pottery Barn furniture if you want to understand better), and as I'm a little older, I prefer timber furniture (I had more steel/glass stuff when I was in my 20's), which is where IKEA fails hardest, because practically all their "wooden" furniture is just particle board/plywood.

So, for furniture I try to use smaller local places that either sell direct or at least are selling locally built stuff (this works in my favour when you consider the above - shipping assembled solid-timber furniture isn't cheap). This obviously doesn't work everywhere, but I detest living in the city so it hasn't been a problem for me so far.

For general housewares like kitchen utensils/etc I don't see a lot of difference between IKEA/<Name your local shop with homewares: Kmart, Target, etc> so it's just whoever has what I want, but IKEA's constant focus on low price also makes me a little wary of anything that isn't obviously just solid steel/wood (e.g. anything with a steel 'head' and wood/plastic/rubber handle, is basically guaranteed to fall apart) because in my experience these items embody 'you get what you pay for'.
