Hey, it’s my first time installing a press-fit bottom bracket (SRAM DUB). I can get both cups started straight, but as soon as I begin tightening the press tool, one side goes in faster and the whole thing becomes misaligned.
Am I better off pressing one side at a time, or is there a trick to keep it straight?

I could be wrong so double check me, but I believe you’re supposed to press each side in separately so they don’t cross hatch like they have for you.
I remember watching a video on YouTube about it but it’s been forever and I’ve yet to need to do a PF replacement.
Don’t press both of them at the same time
Drive side 1st, then non drive side, press slowly ensuring surfaces are parallel
I have done this successfully multiple times, always both together. So you guys are saying I should do one at a time? Why?
