steam vs gog, which game store to buy from?

Hey, so for some time now i had this problem... I have been buying games from both gog and steam... No drm option is good on gog but there are some festures missing from what steam has, for example being able to buy games from trading cards... What should i do? Focuse on buying games from gog and if there isnt a game then buy it on steam? Or maybe just buy games on steam?
