I'd guess that Soakers are more like Enhanced Super-Flex, earlier and hooks more, but not by huge amounts, but enough for your eyes to easily see and your feet and target need some adjusting. GOO/M80 is even earlier and stronger than Soaker and Enh SF, another class of resin, so to speak.
No, I (personally) would not say that pearl Soakers are stronger than other comapny's resin solids. (based on experience with a Thing, an Element and an AU79)
Activator, and Mo's Enhanced C4 (and to a small extent Monsoon) are all different and in different ways from Soaker, Enhanced SF, and GOO/M80.
