what is ordering of ability of all mode of firewall?

i would like to know which mode has the strongest ability to defend attacks.

as i know vlan pair mode is the best one which can defend atomic attack,

but vlan group mode can work well in limited capacity, i would like to whether vlan group mode can defend atomic attack?

if so, can i say that vlan pair mode 's ability is just a subset of vlan group mode?

if so, vlan group mode is the strongest one ?

why my ISP using unpair mode ?

VLAN pair mode or VLAN group mode is mainly how the sensor interfaces are configured.

You can find more information on the same in the link below where they discuss the understanding and deployment of both modes.
