The game is currently on sale on steam, with 30% discount.
No discount on GoG.

The game is regulairly updated on Steam.
On GoG, updates come with huge delays.

Which makes me wonder, why the devs did release the game on GoG at all, since they obviously dont care about potential and current customers on this platform at all.
And yet, they charge the same amount of money...

On sale now. Front page flash sale for a game that is routinely out of date, and not a single post from the dev.
No thanks.

Yeah, the huge lag in updates is really annoying.

We just got the 111g patch on GOG

It has taken long time, but now we have the same build as other platforms
