Hi! I'm playin a lot of spin&go's and first what I can say is that 0.25 s&go its just wasting of your time, much better would be to play more expencive buy-ins, starting from 1$, prizes pools there much higher, at 1$ once time I catch x20, and then higher buy-in - higher chance to get x4 or x6 prize,there paying 3$, prize x6 you get much more often then in lower buy-ins. And about specific of your game in s&go : yes, aggressive is optimally tactic here, but you shouldnt forget to look at game stile of your opponents and to know about ICM of the game. Good Luck!
