Each trailer type has their place. My ‘opinion’ is a bit less than Hay Dude, north of 10k, I like the weight better distributed, but legally on a bumper pull can go much more
A bummer pull will track better behind you in turns as the hitch connection goes the opposite direction of the turn. Up to a certain length the trailer tires will take the same path as the truck rear tires, never the case with a GN, it will always track inside.
Being able to go beyond 90* in a turn can be very beneficial at times with a GN (not recommended often or loaded heavy as it is a great strain on trailer suspension .
Losing bed space with a GN sucks.
GN is overall longer if storage space is a concern.
If you don’t need to haul heavier weight, I’d stick with bumper.
