IQ ( solid ) certainly seems to me to have a stronger shell. However I think the core differences are the biggest factor. Low rg and differential makes the IQ smoother off the breakpoint than the V Max no matter what layouts you are using.
The smooth rolly reaction makes the IQ seem to be much more versatile, and a better control ball on tougher conditions. It will also burn quicker for higher rev guys on hooking conditions.
Tamer cover also makes Versa Max a good control ball on more hooking conditions, but it will squirt sooner than the IQ on heavier oil.
IQ pearl reacts a lot different for me than the solid. Most guys I know like one or the other but not both. Higher rev guys like the pearl. Lower rev straighter guys like the solid.
