I have various ones but not a single favorite. Depends on what I'm cooking and the footprint of the food. For example, cooking some pancakes I use a wider one. If cooking something with a smaller footprint I use a rectangular one. I prefer the silicone cooking utensils. They are durable, can handle the heat and don't scratch up the pan. I generally use cast iron pans and aluminum nonstick pans.
I typically don't use the silicone ones on with the grill though. If grilling outside on the grill slats I'll use metal ones. The metal ones I have are Pampered Chef ones if I remember correctly. Stainless steel, thick gauge and durable. If I have to guess they are around 20 yrs old. If grilling outside using the cast iron pans, I'll use the silicone ones.
New apt has a gas stove. I haven't cooked on a gas stove in years since my previous houses and apts didn't have natural gas connections. I like cooking and baking with natural gas. Instantaneous heat and better control, less expensive to run, can still be used if there is a power outage. You could even use it as a temporary gas heater if there is an electric power outage. Current stove has 4 burners and this mini nonstick skillet thingy in the center. It's perfect for cooking some pancakes, eggs, grilled sandwiches, toasting some buns and stuff like that. Use a silicone spatula so you don't scratch up the nonstick coating.
