Oh boy this is bad. Not even touching topic properly.

There are 3 good sumons in this game:

Rate Up/Awakening Rate UP sumons, they have increased rate for SR/UR. You should be saving PS for this one.

Current itteration of step up summon. if you have some gems/money to blow you get GUARANTED UR at second lap. And considering ammount of sumoning done you should get 1-2 more URs. Both new step ups also featured guaranted UR that can be awoken, so you are getting top of top for your money. Added benefit of step up is increased SR/UR rate with each step.

Flip Summon, 300 gems get 1 card and see 5 next. This is good deal. You can "probe" RNG for cheap and just grab UR when it shows. But again needs bunch of cash/gems. But I would say setp up looks like better deal if you blow cash. Guaranted is guaranted..
