Maybe not

You know, a lot of props marked as having 6" pitch aren't the same as other props marked as 6" pitch. You will have no clue what pitches the mfg chose to put into his blades to get them to pull what he considers appropriate for a 6" pitch prop. He might be designing for any rpm he thinks is right. And he has no idea what engine you're going to run or what airplane you're going to be flying. And he usually has no idea what the other prop mfg's are working with as well.

The only answer to whether one prop is going to be better than another on your airplane is to try both.

Are there differences between props? Yeah, some carbon fibres are stiffer. Some are so thin they flex at the tips. Almost all nylon are reinforced. Some are stiffer than others. There is a new line of props that appear to be reinforced nylon and seem to be as rigid as steel. There are others you can twist in your hands.

Does your 46AX need a stiffer prop or a more flexible one? Nobody really would have a way of knowing without trying the carbon fiber one you wind up buying against the nylon one you wind up buying.

Our hobby isn't sound byte simple unfortunatley. Your question isn't one that'll be answered with just a yes/no and the answer have any real hope.

Just looking for a general idea?
Whichever looks like there was more care in it's mfg is probably going to operate closer to its' specs, whatever the mfg used for specs. And may work better for an airplane that matches those specs. And an engine that matches the specs.

And only way to actually have a clue is to test 'em on your 46AX on your airplane with your fuel and at your field.
