Nothing where image quality matters that much, but something that can cope with twilight would be handy.
The mk3 does have a newer processor and ND filter which may help prevent blown highlights.
There's also the Canon G7 X mk2 which is similar price and features, and the Panasonic Lumix TZ100 which is better in some ways and worse in others. No doubt combining the three would give me just what I'm after. :/
