I own a Strike Zone and the Scorchin' Inferno. My personal observations are that the Strike Zone is much more angular at the breakpoint, whereas the Scorchin' is strong, but smooth.
I really love the Strike Zone, and feel that for the past year and a half, it's truly one of the best balls from ANY company. I leave mine dull and have never found too much oil for this ball. I'd highly recommend this one.
