OK.... I'll add this.... this is a game played with EVERYTHING... from phones, to computers, to cars. If you wait, there will ALWAYS be a replacement looming on the horizon, one that is better, faster, etc... you name it. It would be different if the Note 6 was right around the corner, but its not. It is a good 5 or 6 months away. And even then, once the Note 6 is released, the Note 5 should have a pretty big drop in price, adding a whole new element to the equation.
I would say this... if you want a new phone, and want it now, and want a Note... get the Note 5. If you have no issues waiting until October (more or less), wait for the Note 6.
