Oh, come now, Michael! Aren't you overstating your case just a wee bit? I have never had frozen asparagus, carrots, spinach, broccoli, cauliflower, squash, Brussels sprouts, or just about anything else that I can think of that comes anywhere near the quality of the fresh veggies I can buy just about any day at the supermarket. The supermarket veggies are also significantly superior in texture -- freezing significantly degrades the texture of most veggies, IMO. Of course, if something is out of season, frozen may be the only alternative. Still, I'd almost always pick whatever fresh veggie is available before opting for frozen.
That said, I do keep frozen peas and green beans on hand as fill-ins for when I'm out of fresh, and I use frozen spinach in a lot of dishes, such as lasagna, simply because it's convenient.
