None of them are 'bad' to me, but I think
Ellen has such a classic, understated beauty to it.
Elaine seems dated to me but it is pretty. The rest don't really strike my fancy, but again, none are bad.
I pronounce
Elena like
Elaine with an 'uh' on the end.
If I had to rank them it would be:
Ellen ElaineIlenia
IlincaElenaIleana (just because I'm tired of hearing -iana names)
