I did pass through SEN and FTL lounges at all the other LHG hubs (+ LO and LG) and in particular Zurich I'd say looks much more enjoyable than Vienna HON, as far as I can tell. (Provided you aren't stuck in A in a time that can be described by anything than "far from busy"...)
Quick look in is not quite the same as spending time there, in the VIE HON lounge

Food & Beverage is way better than in any SEN lounge & it’s never busy, so it has space, tranquility & privacy
