My family has an iMac g3 256mb ram 400mhz. Would it be more responsive to run 10.2 Jaguar or 10.4 Tiger? I know the min ram req. jumped from 128mb to 256 mb between the two but also that each upgrade to the os has been optimized to run more efficient. So which one would be the best solution in terms of quickness and all the software we need is compatible with 10.2 so no issues there.
