Shakepay vs Newton - final costs

I'm fairly new to the game and wondering if anyone has any experience using both platforms and can tell me which would be cheaper to use at the end of the day after purchasing and transfering to hot/cold wallet. I understand they both have their own base costs plus spread and newton required you to pay gas fees. Wondering if the spread with Shakepay ends up being cheaper at the end of the day after transfering to wallet or if newton comes out cheaper.
