It depends IF you plan to 'someday' add more RAM.
The F3-12800CL9D-8GBXL are fine, but when using 2 Kits for 4x4GB often they'll only run together at DDR3-1333 Frequency.
Both the Corsair sets listed CMZ8GX3M2A1600C9B and CML8GX3M2A1600C9 are fine, I would choose the
CMZ8GX3M2A1600C9B only because I know they'll run together in a 4x4GB and at Rated Frequency/CAS and there's 'some' room for OC'ing above Rated.
I do also like the Kingston HyperX T1 KHX1600C9D3T1K2/8GX but at least in the USA are out of production/discontinued. Also the G.SKILL F3-12800CL7D-8GBXH - you need to manually set the DRAM Voltage to 1.60v but they're really fast but expensive.
However, yeah IF you can get the F3-12800CL8D-8GBXM that's best.
Though I 'sort of' agree with Thomas's article, here's some additional and 'rated' sets -
