GFCI will save people from direct shock , but won't always stop a fault from say starting a fire. Example a damaged wire arcing the live and neutral (not a dead short) won't trip gfci, there is no ground fault because the power is returning over the neutral as it should. And since it's just a partial arc short it's not going to draw enough to trip the main breaker so it can just sit there and get hot and catch fire.
Technically we now have AFCI to try and detect exactly that, but it's still relatively recent and generally very expensive to implement.
All that said, I prefer the g-type outlet simply because of the giant plug ensures a nice, proper, secure connection, and isn't shaped in a way that lends itself to being particularly damaged. Even if something lands on it, it's profile prevents it from being ripped out of the socket. Whereas the other socket types tend to stick out quite far from their socket and have a tendency towards being yanked out of it. Obviously I'm partially overreacting because I'm dealing with the absolutely fucking garbage type B Outlet I just want an outlet that will finally stay secure
