Sailor's trendy, and Sayler's just a tryndee misspelling of that. In any form, it's ugly, boyish, babyish (can you imagine a Judge/Mayor/President/Doctor Sayler Smith? or a lover calling out "Sayler!" while lovemaking?), and extremely datable to me. I predict it will be just one of the currently tryndee names that will be seen as Bertha-ish in 50-75 years.
I'm sorry to be so harsh, but those are my honest feelings.
