I would cast a vote for the Remington PLHP bullets as they are the only bullet I've spun to disintegration in a 1/7 twist 223 barrel.
They hold together in a 1/9 twist barrel and are devastating on critters.
The Speer TNT pretty much detonates when it impacts game. The pieces I’ve found aren’t much more than course sand. I haven’t seen them for a good bit though.
