Both very good. I use the Pulsar Comp 3 myself, and my touring car racing buddy uses the Orion. We both are impressed with our chargers, and as you say similar specs.
Reason I settled on the Pulsar 3 was first it was in stock at MK Racing, great price too. Secondly it's lifetime warranty makes it very appealing. Really though not a lot between them, go with which ever ones tickles your fancy.
