I've done both, only once with neve and a few times with Brooke.
Brooke is definitely better looking and sexier in my opinion. She's also very enthusiastic, eager to please and a great fuck. Definitely the one to go for.
I've never had a problem with Brooke taking a good mouthful, she even looks a little sad the odd times I've covered her tits or arse and not in her mouth!
They're both well reviewed and I guess it will come down to personal preference but Brooke gets my vote
