universal couplers are because the compressors get sold all over the world, they usually leak air.
Pick a style you like and as said above use a good sealer tape. I'm using the Milton M type only because I've been using them for years and have dozens that would need to be changed. There are much better systems and the new style you cant release by kicking are nice but pretty spendy. I would change out the fittings on the compressor.
Sad reality buying a new compressor and needing to update fittings immediately.
