I've tried a lot of Teflon and non-teflon non-stick pans. I cook a lot and put my pans through a real workout every day. I saute and pan-fry so much I have doubles in every size: 8", 10" and 12", plus a griddle pan and a crepe pan, as well as two sizes of chicken fryers and three sizes of stew/stock pots. (I have 2 saucepans - everything is non-stick - but rarely use them.)
1) The non-teflon (the ceramic and "granite" coatings) seem to only stay non-stick for a short while. I mean short - within a dozen uses they start sticking even with oil/cooking spray.
Once they start sticking, they're hard to clean. Scrambled eggs became a major pain, even soaked with soapy water.
2) Teflon-type (which is now often described as non-PFOA) is used by many mfgs. I always use cooking spray, as well as oil when necessary for browning. As the non-stick starts to wear, I relegate it to the "browning/frying" duties. To me non-stick's real use is in the clean-up. I have burned the crap out of a non-stick pan at occasional inattentive times. An overnight soak with hot water and soap, covered and let sit....all the burned stuff simply slides right out. It won't be as good at "like new" non-stick, but it will be fine for everything but frying eggs.
I've had the best experience with these two brands:
- Circulon. It's the top of the line brand from Meyer Corp. I don't care for the new redesigned shapes of the saucepots, but it's very durable. I like the Innovatum line best as it goes through the DW easily. I like the size/shape of the stewpot. The 12pc collection only has the 6 qt size, however. The one I use the most is the Acclaim line's Stainless Steel Nonstick Wide Stockpot in the 7.5 qt size, which has to be purchased separately. However, I'm thinking to upgrade to the similar shape/size in the Innovatum line, as I like those handles much better. I really dislike the Acclaim's foam-style handles; I don't think they're that durable.
- T-Fal: But NOTE: T-Fal has cheapened up on their lower-tier frypans. The coating is still extremely durable - one of the best, in fact - but in the 2 lower-tier lines, the wider the bottom, the more likely it is to warp. My 12" T-Fal has warped evenly - it bows upwards towards the center when heated. You can tell when putting oil in the pan - as the oil (or any liquid) starts to warm, it slides off the center to the outer edge.
You can buy the top-tier T-Fal line which is T-FAL Ultimate Hard Anodized Titanium Nonstick. It's a thicker bottom so I would guess less chance of warping on wide pans (small ones are no problem for any coating). It has a special coating so unlike most hard-anodized cookware, this can go through the DW.
But it's not cheap - there's only a $10 difference between the 12 pc T-Fal and the 12-pc Circulon Innovatum, and I like the Innovatum's pan assortment better.
I have had very poor luck with Calphalon and surprisingly, even All-Clad.
Anyway, YMMV. This has just been my personal experience.
