I TRY to use the same brand (I've pretty much settled on SR), but it doesn't always work out that way.
The way I figure it, the cables were designed and engineered in their lab/equipment space using the other cabling from their own brand, so it stands to reason (at least to me) that the cabling would be "tweaked" to match.
Again, doesn't always work out that way.....but I try to stay in my lane, whenever possible.
