I have them all. I really like the Hard Rock. Classic Rick is good too.
I think they all are good in their own way and so like the 1000 monkeys with typewriters eventually you could make a masterpiece with all of them.
Disclaimer: I have 14 basses and have been playing bass for 53 years (not very well but I play it very old school garage band style) and so the use of EZBass is not for completing projects but to explore options and get inspiration when I'm coming up short.
