plz help to choose the board

Im 6'4 and i weight 180 and i few days ago started learning how to surf. I was thinking about buying a board many websites say that the soft board would be perfect for beginner but i read somewhere if u planning to do it pretty oft and u're sure that u will progress fast u shouldn't buy a softboard u should buy a pop-out right away.I guess next 2 weeks im going just rent softboard but after that im planning to buy a pop up and which should i buy
-thanks
