This new BW turbo looks very promising, but it's hard for me to compare to other stock location turbo's due to the fact that you need a new uppipe and downpipe to be able to run it. If someone already has an uppipe and downpipe (as many people do who are looking to upgrade their turbo), then it is getting dangerously close to rotated territory.

If this turbo meets your power goal, and spool is your absolute primary concern (and you're willing to spend the money to get it) then this might be perfect. If budget/simplicity are your main objectives, then there seems to be similarly performing turbo's that would work with the stock up/down pipe. If you want big power, then you're probably looking rotated. This turbo kind of seems to fit into a middle ground. Maybe it will be perfect for some (or possibly many) people.

Yeah, the TopSpeed dyno plots for the Dom1.5XTR look pretty similar. Stock motor, stock TMIC as well. The TopSpeed car had a full exhaust system though. See below (note the rpm's where the two turbo's hit 200ft-lbs, 300, 400: they are basically identical).
