Both chargers are fine. I use to have both, i bougth an ICE first, than i sold it and buy the Pulsar later, now i'm with a Integy Indi Dyno 16X512.
The ICE have some more fine adjustments than the LRP Pulsar 3. But the Pulsar is easier to use, and achieve at least the same results than the ICE, and even better most times. In the overall, i like more the Pulsar.
