Asking is the way to learn.
The extra ram is there if and when it is needed. Good job! Two thumbs up!
The difference is little no none (nothing youll ever notice either way) so I would call them a tie in regards to speed.
But, it does look they will all play together well :)
I would run a Memtest on it, just to be 100% sure all is stable and well.
But from the looks of it, I would keep both kits. More RAM is always better.
And if both kits are stable & play well together, that would be the best way to go IMHO.
