I still find the first one more readable.

Maybe it's just me, or maybe it's a matter of habit, but for me the changes from lowercase to uppercase and back are a kind of hurdle that make my brain pause a moment. The second example is much more cumbersome to me to read and parse.

Same for me - I find the use of upper case keywords like this jarring in SQL. It seems quite old-school, like reading COBOL!

It's probably my repressed memories of FORTRAN that cause me to react so strongly to UPPERCASE.
