How good are pachyrhinosaurus at bullet draining?

I know stego is great but I don't know about pachys.

I've heard they're good at certain angles. They have as much hp as a trike, but they have more armor on their saddles, and they have the same bullet damage resist on headshots, I believe. I assume to use them well, you'd want to tank turrets placed on level with the head. I'm pretty sure the damage resist on the head is the same as the stego's plates' damage resist.
After the update to turrets say... maybe a year ago? ...Turtles are pretty poor, even on bases with carelessly set turrets.
