DDR4 3733*(*O.C.)/ 3600*/ 3500*/ 3466*/ 3400*/ 3333*/ 3300*/ 3200*/ 3000*/ 2800*/ 2666*/ 2400*/ 2133
Sometimes it's like arguing which PSU is better only to find out that they were both made by the same OEM and the same platform and differ only by paint job and stickers.
And like PSUs, Corsair 750 watter doesn't tell us much, and here, you haven't listed the CAS
But from what I see, the cheaper Gskill has faster speed and faster timings (15) than the Cruial's slower speed, slower timings (16).... speed, CAS and price all favor the Gskill.
It's just about impossible to judge reliability based upon any users experience as the sample size is just too small
based upon samplings in the thousands (european returns between 6 and 12 months of operation), Crucial looks much better having 38% of the failure / replacement rate as Gskill

- Crucial 0,50% (contre 0,57%)
- Kingston 0,65% (contre 0,36%)
- Corsair 0,81% (contre 1,20%)
- G.Skill 1,30% (contre 0,97%)
But it's not as important to look at the company as the specific models as just a couple of bad models can swing the overall rate in a big way.
I prefer Mushkin models myself but vendors have an extremely hard time keeping them in stock. Was a time for example When Corsair, GSkill and Mushkin were all using superior Hynix chips for DDR3-2400 but Mushkin is the only vendor left using them. That's what makes it hard to pick by vendor and even by model line as Vengenace Pro version 4.51 was Hynix and 4.52 was not.
For DDR4, I try and get these Mushkins Redlines when I can tho on Skylake using the preferred 2x8 sets. Because if supply and demand the Muskin proces have risen substantially and are hard to justify at this point in time.... $140 last time I looked for 2 x 8GB 2666
