[name]Diana[/name] is a lovely, elegant and feminine name with royal and mythological associations. All of the other variants don’t feel as fresh to me. [name]Diane[/name] was a 1950’s era name so it’s “dated” to that period of time for me. The spellings with two n’s are overkill and [name]Deanna[/name] is more 60’s-80’s style so it’s “dated” as well (even though there was a golden age Hollywood actress named [name]Deanna[/name] Durbin).
That made me feel old as well! My goodness, was it really that long ago?
[name]Diane[/name]/[name]Dianne[/name] is centuries-old and should not be relegated to 1950s-era status…think [name]Diane[/name] de Poitiers (1499–1566). Also, check Ancestry.com, and you’ll find numerous Dianes and Diannes from the 1800s and earlier.
I have a friend named [name]Dianne[/name] and I much prefer this spelling compared to [name]Diane[/name]. I also have an Aunt [name]Diana[/name] not a fan of this name at all!
I think [name]Diana[/name] is beautiful and should be considered more of a classic. love the goddess association. 
I find -anne suffixes to always sound harsh and nasal. So [name]Diane[/name]/[name]Dianne[/name] does poorly for me.
[name]Diana[/name] is nicer. I’m no huge fan but it’s a pleasant name with a good bit of historic weight to it.
Personally there’s many other [name]Greco[/name]-[name]Roman[/name] pantheon names I find far more appealing, starting with [name]Diana[/name]'s Greek analogue, [name]Artemis[/name], and continuing for about fifty other names before [name]Diana[/name] ranks. [name]Artemis[/name]/[name]Artemesia[/name] would feel far more ethereal to me than [name]Diana[/name].I
I think [name]Dianna[/name] with two n’s looks weird. I say that as a person with a two-n name who ought to have a one n - ana instead of anna specifically - and it’s been an enormous pain in the ass over the years and I still think about legally fixing it to the classic spelling. [name]Dianna[/name] has no advantage over [name]Diana[/name] that I can see.
[name]Diane[/name] is somewhat common where I live so it feels dated and middle-aged. [name]Diana[/name] on the other hand, I think is lovely and fresh. I have never met a [name]Diana[/name] and it seems like a very underused classic. I had mentioned it to my hubby, but he didn’t like it. I like it spelled [name]Diana[/name].
No I love [name]Diana[/name]! It is so classic and pretty. And I like the “[name]Dianna[/name]” spelling as well. I also like [name]Diane[/name], but not as much because I think the “a” ending is nicer. The only one that I don’t like that you mentioned in your title is [name]Deanna[/name]. That doesn’t strike me as classic.
I love [name]Diana[/name] - it’s on my short list. But not a big fan of [name]Diane[/name] or any of the other variants.
I love both. I think for a first name, [name]Diana[/name] is a little prettier. We will use [name]Diane[/name] as our middle name, if we have a girl. (It’s a family name).
I love this! It will always be stylish and classic. It also has an amazing namesake- [name]Princess[/name] [name]Di[/name]!
My favorite variation is [name]Dianna[/name]. I also like [name]Diandra[/name].
[name]Diane[/name] is my favourite. It’s a timeless classic and far more universal than the other variants. [name]Diana[/name] is a little too fussy or prissy sounding, an extra ‘n’ anywhere just looks like a misspelling and [name]Deanna[/name] just sounds like it is trying far too hard.
[name]Diane[/name] is more historic than any of the others and more solid and complete sounding than any variants.
