I have the ICE HV80. I have no experience with anything else, but like the data logging. If you already have a data logging system, then I'd go with the lighter or cheaper option depending on the project. They both work.

In agreement with Joe L, I talked to Castle when setting up my system, and was told for our style of flying to turn off the current limiting features. It is rated for 80A continuous, but when you go through the settings you'll see that the firmware is set to handle peaks of 100-120A, and then you can disregard even those limits.
