Vanessa Marshall: Vanessa has experience with deep and strong voiced females so she was a great choice. Vanessa gave a good voice for Gwen's Diamondhead, having a lot of elements of Jim Ward's Diamondhead voice but keeps a feminine sound to it and Megan Smith's Gwen personality but still makes it her own performance. It's a good performance from a talented actress.

Ashley Johnson: Ashley doesn't get to do a lot of different voices so this should have been a great showcase of her range...should have. I don't want it to seem like I'm bashing Ashley as an actress as she is quite talented but she comes off as a woman trying to sound like a man, it's rather awkward in some lines and inconstant as well. I will say though, it's funny how sometimes Ashley sounds deeper as Diamondhead than Dee did as Diamondhead. So while Ashley had an admirable attempt I will sadly say she's the weakest.

Tara Strong: Tara got only one line as Diamondhead so sadly she is at a big disadvantage...but I think she worked against it and delivered a good voice. While focusing more on the feminine side more than Vanessa and thus isn't as deep, Tara still gives a nice deep and strong voice. I would love to hear more from her and show off more of Gwen's personality.

So in the end, I felt each actress did a good job in their own way but I have to give it to Vanessa. I will say that despite her limited material Tara is second for me and that puts Ashley at third.

Vanessa though Tara is pretty close, Ashley is kinda forcing it

Autovolt's right that they're all a bit mannish, but I guess Vanessa's most fitting to me in terms of her overall performance, Tara's got the most natural delivery despite the voice being a little generic, and Ashley's delivery is pretty inconsistent at times going higher and then lower again.

So I'd go with Vanessa first, Tara second, and Ashley in third on this one, honestly.

They all sound kind of mannish though Vanessa has the most personality and the best performance of the three.

Ashley Johnson sounds a bit too awkward at times.

Tara Strong I'm sad she only had one line because she sounded the most natural.

It's a close one but I'll go with Vanessa.

Man....I hear way too much Irwin from Vanessa's take, but its the best in my book.

In defense of Ashley the reason she probably to sound like a dude is to make her sound make authorative, and more muscular, I mean she's an inexperienced teenager, so almost any teen would probably do that, and that probably the best she can think of, she's not exactly Wonder Woman or Hawkgirl, plus she's probably not even comfortable in her form either.

What I feel defines Diamondhead voicewise is that it's "crystal-clear" despite being deepened by effects. Marshall just didn't give me the impression that she's Diamondhead.

Tara for me.

Going with Vanessa Marshall. She does a good job at doing a feminine version of what Jim Ward did with Diamondhead.

Ashley Johnson is OK, but it seems kinda awkward. In the story it was supposed to be kinda awkward cuz Gwen and Kevin were turned into aliens when the watch malfunctioned so that could play into it a bit.

Tara Strong sounds rather good with jut one line. I'd really like to hear more of her Diamondhead.
