If you find Synergy to never be a concern, or rely on Slow tier supports, run with Support-focused so you don't need to worry about slow-charging Supports.
If you find that you're just shy of starting with full Synergy round 2, and find yourself often winning round 1, Special is the best matching cheer for that. Bonus points if you have a slow Support that you prefer.
If you have a Support set where you feel you're comfortable mixing up against any opponent, pick Standard.
Really cheers should primarily be considered for your Support or for topping off your Synergy. If Synergy is a problem beyond that you should reconsider your core strategies.
