I think Leraje is better than the Psychic Bounder. Leraje can kill many targets in a masochist deck (more the longer the match goes) that have high attack but low defence and has ok stats even without the boost. If I had it it likely would go in my deck that currently suffers in the platinum rank (in parts thanks to a royal Zeus which was a weird pull) and has the one field spell that boosts the attack of your monsters x200 for each element in the GY. The Psychic Bounder on the other side only works in rather rare situations because it sadly isn't protected by its own effect. If your opponent does read (ok here is your chance :)) it should be usually gone without accomplishing much more than any other 1.7k attack card.
