as the op is a SPG Platinum and he is now a hilton gold, i compred plat to hilton diamond.

even as a diamond in hilton program you almost never get a suite upgrade.

hh gold vs. spg gold sure the hilton gold is much better but spg platinum with the suite upgrades is in my eyes one of the best things spg offers.

i got only one suite upgrade as a diamond (which was at the conrad tokyo...)

so i still say, SPG plat is better than HH diamond for suite upgrades.

i agree that hh gold is better than spg gold , which means nothing.
