I would always purchase the physical disc version over a digital version given the choice. There are pros & cons of both.
Discs can be scratched and lost but you'd have to be a total dumbarse for that to happen.
Trouble is digital versions completely lose their value once you've redeemed the code so the only thing of value is the statue or whatever else came with the CE. Also you never really own the game, you just 'allowed' to play it.
I know everything will go digital eventually, but in the meantime I'll keep on collecting the disc based versions.
