gog features summer and winter sales every year and offer quite a lot of games at lower than retail prices.

Pro Occasional free games
Every so often, GOG will have a game listed as free to add to your account.

GOG may charge more in some regions as publishers request so. But in those cases they give the extra cash back as credits for buying another game.

Cons
Con Risk of stolen keys
As G2A is a user-driven market place, not all keys sold may be legitimate. Anyone from anywhere can list a key for sale à la eBay and Amazon. However, like eBay and Amazon, G2A provides the seller's feedback rating and number of sales prior to purchase.
Con Opt-out service on checkout that is easy to miss, which charges and subscribes the purchaser to something they may not need or want
Many people have reported issue with the "Shield" subscription service, that seems to auto subscribe users when purchasing keys. It has also been reported that is is pretty difficult to get this subscription turned off, which can be frustrating for those that never wanted it in the first place.
Con Linux games distributed as installation scripts
Installation scripts have a lot of bugs and dependencies. Packing games in archives would be better. Extracting archives from installation scripts is possible, but difficult.
Con Many games only for windows when they also have a native Linux version
The Linux library on Steam is far bigger than in GoG, many titles have its Linux version both in Steam and its respective web page, but GoG only lets buy the Windows version.
Con No Linux client (yet)
They say it's coming. And meanwhile you can still install Linux compatible games directly.
Con Limited, often dated, library selection
Con No compatible support with (Steam) achievements
Steam has achievements that many appreciate. Unfortunately, those same achievements are not available when you buy the GOG version of the same game.
