Personally, Aspen and Taarna are both a little too cheesecake to display in my apartment. I like my large statues sexy, but not nearly naked.
I have the Batwoman EX and she looks like a badass with the dual pistols. The statue has some real weight to it and it looks great, especially if you can get her cape to look just right.
I actually am a longtime fan of the Heavy Metal animated movie, but the Taarna PF just didn't do it for me. The colors look wrong, and I think the definitive Taarna statue should depict her riding her pterodactyl-like thing.
I do really like the Aspen statue, but I have no connection to the comics. I tried reading it years ago but could not get into the story.
