I much, much prefer Glasgow Club. Swim systems are still a bit of a mess but between Tollcross, Gorbals and Emirates Arena there are plenty of classes at decent times, never usually too busy, and good equipment variety. And it's £27 a month instead of £70.
Gorbals also has badminton hire for £5/hr and Emirates has the Refresh Spa for £10 per entry (but that's still closed just now).
