The good news is, there's really no "wrong" answer between the 2.
I've taken a bunch of whitetails, a couple Mule-Deer, 2 Caribou, and an elk w/140gn TSX/270Win combo. I've also watched a cousin and a friend use the same combo on elk and multiple deer. The 1st Mule Deer I took @ ~75yds, bang-flop. Fall of '19 I took a Mule Deer with the same combo @ 560yds, Bang-Flop. Both caribou went straight down as did the cow elk I shot.
No, the BC isn't great, but, I get excellent accuracy and mind-numbingly predictable terminal performance with the TSX. If they became unavailable tomorrow, I could happily shoot a partition.
