Gong Carbon vs F-one Phantom Fct

Maybe a dumb question…I want to buy a 1500cm wing foil…I have already a gong carbon mast…I’m btw to buy a Gong Curve 1500cm and change completely and buy an F-one alu Phantom 1480 fct (that I think is better but never tried and it’s aluminium)…at the moment cannot afford any better option…
Someone have tried both…any advice is welcome
