The max power of the move is still the same.Its just that it gets up to the max power quicker.To be honest it takes 6 turns to get up to the same power of x scissor, which most bug times can learn.And if you can survive doing fury cutter for that many turns without any main physical attackers, walls, protectors,fire types or pokemon that resist bug type then you have already won.
So in conclusion it would be much better to just use x scissor.
Hope i helped! And an upvote or best answer would be majorly appreciated :-)
