We just got the about MSA G1's about a year or so ago. We have had a lot of good luck with them coming from the much outdated MSA SCBA prior to that. The frame of the pack it self sits better on the hips, bends and shifts w/ your back w/ an adjustable back plate to user preference. We are in the process of obtaining the accountability system that is built into the pack also. Having used both Scott and MSA, MSA has come out with a pack I think has exceeded Scott. However, as long as I can rely on the product than it's all good.
