A little of both. I spend my mil points on tech, while my admin i save up and dip i use as dev pushing a little. You only have to wait a 2 decades at max thats if it spawns in like Sicily.
 
Push for the renaissance and sell it to wealthier countries. If you unlock the first national idea, it will increase your tax income, but so will dev pushing - and selling the renaissance will do the same. Dev pushing will also make that tax increase modifier more effective later. Additionally, the Prussian government, once you unlock it, favors playing tall.
 
I dev push Berlin to 30 after 1450 for economy boosts and the age objective, but don't go out of my way to go all the way to full renaissance.. If Austria doesn't offer knowledge sharing, it should spawn in Berlin by the 1460s.
 
Embracing renesanse by developing capital might be good. The state needs money, and there is a limit of how much you can conquere.
Also there are some cool era perks like transfer vassal, so getting them faster may be beneficial.
