The main problem with the IM2 is that its flood nozzle doesn't go anywhere in the range department, and blows all your pressure. All the output in the world doesn't amount to anything if it can't be delivered on target. The IM2 can only really skirmish on the small nozzle, which is next to useless. Despite being CPS, I'd rate a lot of AP guns and even PR guns above it.
I had the chance to go 310 vs Blazer in the Chaos round of Moab, this involved trying to turn and fight during a run for my life. The fight didn't last long. The range and output of the Blazer just rained down and the 310 couldn't compete, forcing me to continue running. The 310 can be pressurized faster than it depressurizes, but not on the larger nozzles, which are the most practical to actually use. Shot time is not a weakness of the Blazer, so it can pound away and the 310 user gets forced back.
The 150 has several unique attributes that make it unusually good, even in 2015. No water gun out of the 350+ major models that exist other than the XP 75 can match its extreme trigger repetition rate. Coupled with the huge pump, compact body, lightness, and good capacity, it is able to deliver stunning firepower superiority. You can take 10 tap shots and only need to pump once to get back to full pressure. You can hold down the trigger and let 'er rip, pumping only every now and then. The 150 also has good range for its size, outshooting quite a few larger guns. There is nothing else like this in the game!
With 310 vs IM2, it should be the other way around, the 310 catches the IM2 pumping. The 310 has very long shot time, it's never low on pressure, and if you use the smaller nozzles, it can shoot indefinitely. The IM2's small nozzle has good, but not great, shot time and the flood uses its pressure rapidly. It's a closer battle, IMO, simply because neither can get a significant advantage on the other while skirmishing.
