Yeah to me it's not so much the price right now, because on paper, DEC looks like the better investment...But DEC is so volatile. Who knows where the price will go.
But SPT is community driven. And I can put my tokens to use, curation and delegation helps me grow my stacks. DEC is earned through rentals and game play, which is fantastic...But at the end of the day, I'll always bet on the community :)
