For tiny images like icons, where intricacies are hard to see, it's likely they will almost always be better in svg. Logos especially are generally by nature clean and simple to be able to quickly communicate brand through different mediums. From a practical sense, I'd be hard pressed to find a real logo/icon that wasn't better in SVG. Theoretically, of course there are limits, but the rule of thumb is strong: always use svg for logos and icons.
