I don't write or read SQL too often, but I prefer the ALL_CAPS because it usually lets me know if something is part of the SQL syntax itself or a function or whatever, or if it's referencing a table/column/etc. Obviously not very foolproof, but automated linters/prettifiers like the one in DataGrip do a good job with this for every query I've ever thrown at it.
