I don't always ride flat pedals but when I do they are DMR Vaults. I have tried a lot of flat pedals over the last 10 years, many expensive ones and many modestly priced ones. The DMR Vaults are by far the best pair I have owned. The size and shape are perfect, anything thinner has to use shitty bearings or sacrifice the shape because of the bearing. The pins are great and the pedals are very durable. They also come in a ton of colors... including red.
