I pronounce them differently but with all the Brendans, Brandons, and Braidens I know I can't keep them straight anyway. Of the three I only like
Brandon (and I only like that a little.)
Braiden and
Brendan are rather limp-wristed.
Brandon has some masculinity at least.
Brendan I pronounce like
Brenda with an N at the end.
Braiden is BRAY (like a donkey)-den.
And
Brandon is BRAND-on.
