I've always had an interest in the 375, but the closest thing I actually own is a Winnie in 38-55. Your BB has more potential for sure even though the rounds look almost identical. I do hope you enjoy it, but I think I'll keep my 444. Watching this year's buck fall at 150 yards like he'd been hit by the hammer of Thor is motivation enough to stick with the 444. 444 is an awesome round.
