Felt recoil is a very subjective thing, but for what it's worth I would say the G27 is more like the G36 in recoil where as the G26 and G30 would be more comparable.
The wide grip (backstrap) of the G30 combined with the low pressure cartidge (45 ACP) produces a very controlable gun, which is a large part of the G30s popularity.
As with most things, YMMV!
