probably not worse ergonomic because i type '(' with left pinky and right ring finger and ')' with left pinky and right pinky whereas {} [] etc, i have to use the very same overworked right pinky to distinguish two keys next to each other.
i always have problems with keys that have no obvious dedicated finger position like the middle vertical columns especially 6 and b and of course keys reachable on the right pinky, especially \ and =
