Here is HD's price for 100' of THHN - $28.37: https://www.homedepot.com/p/Southwir...5884/204868304

Here is 100' of tinned marine wire - $27.50: 12 AWG Primary Wire Marine Grade Tinned Copper Black 100 ft

Going with untinned wire in the US is not for cost reasons. Outside the US, it most likely is. I suspect anyone using untinned wire in the US, and having problems with it, is using cheaper stuff than THHN.
