Chase Sapphire reserve (sorry for not making that clear)..
I value sapphire at 1.5 ..so 1.5 x 3 = 4.5 per $ spent
SPG I got a few months ago just about 8.4 cents per points..but i think on avg prob about 3 value spg..not sure... what would you personally use? Chase sapphire reserve or spg paying for an spg hotel..
