Question about Corsair Vengeance LPX
Where is the difference between the two? It's the same but the price is higher?! Cheaper: https://www.digitec.ch/de/s1/product/corsair-vengeance-lpx-2-x-8gb-ddr4-3600-dimm-288-pin-ram-11388259 And what else would you prefer? https://www.digitec.ch/de/s1/product/gskill-ripjaws-2-x-8gb-ddr4-3600-dimm-288-pin-ram-13969582
The difference is actually insignificant, as you may have noticed, only one letter in the manufacturer number is different. This means that the cheaper version (CMK16GX4M2D3600C18) is also optimised for older chipsets, e.g. Intel Z390. Nowadays, however, this makes no real difference.
To the second question: They have identical specifications (also e.g. latency). So there is no difference in performance here. It is best to buy the bars that you like better visually or that fit your system better.
