if it wouldd've been before 2007 would've been a tough question, WWE still had Lita, Torrie, Stacy and Trish, also Kelly Kelly, TNA's Trinity and Brooke (who's now in TNA), but i'm talking about the present, definitively TNA, those are not only hot chicks but they can give great matches, besides the fact that they have different styles and looks and look more real the Beautiful people are maybe the closest to the WWE style of women, but they still look real, Daffney (love her since WCW days), Tara (Attitude era MILF), Hemme, SoCal Val, Miss Tessmacher (Brooke), Taylor Wilde, even Sarita is a latin hottie. ODB and Hamada are the only two now that don't make for eye candy.
then in WWE, who do we have? well, Kelly is still hot, i'll give WWE that and i also like Katie Lea and maybe Alicia Fox and Natalya, but then?... the Bella twins dont look realy hot except for the fact that they are twins lol. Eve torres, generic. Jillian looks like plastic sometimes, Mickie James used to be hot in her TNA days, then McCool doesn't make it for me , Gailo Kim looks fine and can wrestle but it's not that hot, Melina is fuckin' ugly, and Maryse (the one that every WWE mark-TNA hater drools for) would be hot if it wasnt for the fact that she looks like a plastic Barbie, it looks like a cartoon doll..
so TNA has the hot women advantage by far
