Yeah, modern DCS is for different situations than GMK.
Modern DCS has very thin walls, they reveal more of the switch's operation.
For light tactiles, DCS is sometimes better than GMK. Especially with MX Browns. They also sound better than GMK on my MX Brown board.
Old [1980s WYSE] DCS is actually very thick, some thicker than GMK. Still better with MX Browns.
As others have said, DCS is more rounded at the corners. Row-wise, I think DCS is like the classic R0-R5 Cherry sculpt, and then some.
