Im a 5'9 150 lbs male. would a 17.5 or 19.5 iron horse maverick 3.0 fit me better?

I am 5'9", I ride a 17 inch and its perfect fit for me. I tried an 18 inch and it was rideable just not quite as comfortable. It all depends on what feels better when your riding it. Although, I wouldnt think you would fit on a 19.5 inch.
