I would do Atlassian because it's real SWE internship that will either result in a return offer, or be helpful in getting an internship next summer.
From my experience, if you do Google STEP and don't get a return offer (I have no idea how common that is or not or if it's possible) that just having Google STEP on your resume won't look quite as solid as Atlassian SWE
But that said, you're in a good spot to have this choice and if you put your heart into either one I'm sure you'll do great next summer too.
