My personal minhag each night is to count twice (I say the bracha only once.). I say HaYom Yom Echad LaOmer. HaYom Yom Echad BaOmer. I know that, in truth, one is yotzei either way, but for two extra seconds each night, why not be yotzai both shitos?
I do the same, based on a recommendation I once heard from a certain rov. I wonder, since as you mentioned, you’re yotzei either way, if there’s really a point. Isn’t it comparable to R’ Chaim’s esrog shailah (if you have a m’hudar with a shailah on the yichus and a m’yuchas which is not so nice, take the nicer one first, since once you’re yotzei, you can’t add hiddur.)?
