Mainstays 3-Piece Nonstick Skillet Set vs Blue Diamond 10" Ceramic Nonstick Frypan

Buy the Blue Diamond if you want one pan that lasts and can take metal utensils. Buy the Mainstays set if you need several pan sizes for everyday cooking and don't mind replacing them sooner. The Blue Diamond has a ceramic coating, a forged warp-resistant base and oven-safe construction, and its 4.5 rating from over 7,200 owners backs that up. The Mainstays set is lighter and simpler, with a 4.4 rating from about 985 owners, but its two-layer coating is the weaker part.

  • Choose the Mainstays 3-Piece Skillet Set if you want three pan sizes (7, 9 and 11 inch) for daily cooking and prefer lightweight pans you can put in the dishwasher.
  • Choose the Blue Diamond 10-inch frypan if you want one durable ceramic nonstick pan that is metal utensil safe, oven safe and built to resist warping.

Questions and answers

Which is better for everyday eggs and pancakes?
Both work, but the Blue Diamond releases eggs more cleanly and tolerates metal spatulas. The Mainstays 7-inch pan is handy for single eggs.
Which lasts longer?
The Blue Diamond. Its triple-layer ceramic coating and forged base are built to outlast the Mainstays two-layer coating, which wears with heavy use and dishwasher cycles.
Can I use metal utensils in either pan?
Only in the Blue Diamond, which is rated metal utensil safe. Use wood or silicone in the Mainstays pans to protect the coating.
Is the Mainstays set worth stepping up from?
Step up to the Blue Diamond if you cook often and want one pan that holds up. Stay with the Mainstays set if you need several sizes and replace pans periodically.
Can either pan go in the oven?
The Blue Diamond is oven safe. The Mainstays skillets are not listed as oven safe, so keep them on the stovetop.
Are either dishwasher safe?
Both are, but hand washing keeps the nonstick coating working longer on either pan.
