I was also in the market for a new tender this winter. The BRIG's seem really nice, well built and look good. For me it came down between the BRIG and a Highfield Sport In the end I ordered the Highfield as they are lighter and I liked the layout better. My previous tender was a Highfield Classic (open boat tiller steer) that we love.
I like having the walkway between the console and the tube clear and not blocked by a seat, as well as having the seat in front of the console face forward, not to the side. I also like the storage under and behind the seat, its wide open and should be relatively dry. In the end its all minor and personal preference. We spend a ton of time in our tender and really looking forward to be able to explore further away and knee and wakeboard from it.
