I carry one of iPhone 5, Pentax K-7 or Olympus OMD EM-M10. The iphone is alright, the Olympus is pretty impressive for it's size, but the battery doesn't last that long, and it always feels a little delicate. Rhe Pentax is a mixed bag - with the right lens and in good light it's terrific, and the battery last forever (relatively speaking). It's also built like a tank (titanium chassis) but that means it's heavy. And it low light it's not great.
I think if I were buying a compact to keep in a pannier, I'd get a Canon S90 or similar. It has an 'oversized' sensor - i.e. bigger than in most cameras of it's size, plus it gives you quick and easy ways to control the aperture, shutter speed and ISO. It's got a decent lens too. And because it's 8 years old, you can get them for about £40, so it's not a massive loss if it gets dropped, squashed or whatever.
