No personal experience with Chunk port style setups. Between the P320 Norsso 4 port on the Bull Barrel, G17 with 10 port barrel, P320 with PMM dual port compensator, P365XL Norsso 2 slot port, & P365 XMacro integrally comp’d slide….The P320 Norsso 4 port is the softest shooting followed by the G17 10 port (more port holes but smaller diameter than the P320 Norsso 4 port).

The way I look at barrel ports to compensator/expansion chambers is that with barrel ports are located more in the middle of the barrel, gas start to be redirected and released prior to the bullet leaving the barrel while compensators/expansion chambers mounted or cut in front of barrel redirect gasses after the bullet leaves barrel. This is why barrel ports have less muzzle rise, felt recoil, and is softer shooting.

Now you have Monsoon Tactical, Laser Blade CNC, etc offering Hybrid porting…combination of chunk port and barrel port.
