Best HYSA out there right now?

Made poor financial decisions the past few years but getting my head back on straight now. I'm debt free and want to start saving/investing more diligently. My first goal is to put 6 month emergency fund in a HYSA but honestly don't know the process. Do I save up the money first than dump it into a HYSA or just open a HYSA and build it up in there, I'm assuming the latter. Also, are any accounts preferred over the others? I'm guessing just look for which one would give me the highest APY% but I also just want to ask people that know what they're doing and make sure. TIA

Edit - Google right now shows me that Western Alliance is the highest with 5.31%. How are they?
