First the sibset: Like the names, but too many 'vs' together for my taste.
I actually prefer Jevgenij:-)
But from your list
Evgeni, since it looks easier for an English speaker. The name is nice, but it makes me think of a novel in verse Evgenii [or
Yevgeny] Onegin (Jevgenij Onjegin in Croatian) by
Alexander Pushkin, which I hated in high school when we had to read it.
