I have not been able to get on Rhino Rally, but would love to know what people think of it. Is it better then Kilamanjaro Safari?

Here are some number:
Kilamanjaro Safari is 20 minutes long
Rhino Rally is 8 minutes long
Kilamanjaro Safari is set on 100 acres
Rhino Rally is set on 22 acres

know that Busch Gardens was making the Rhino Rally more of a thrill ride, that would account for the shorter ride time. So what does everyone think? Anyone rode both?
