Which one would be the best for gaming? 

[Eigenvektor]

3600 MHz is faster, and CL16 @ 3200 is the same absolute latency (10ns) as CL18 @ 3600, so they are equal in terms of latency. In this case the 3600 would be (slightly) better.

 

~edit: However the sticks you linked are both 3200 or rather the exact same product?

Oh crap my bad. 

 

Could you tell me what the difference is between these (Which all cost different amounts and are listed as different even though specs are the same)

And this one (3200, CLS of 16)

thanks a lot

If you look at the part numbers, you can see they some have a slight variance (links to official specs from Corsair):

 

CMH16GX4M2D3600C18 – default: 2133MHz, CL 15-15-15-36 – XMP: 3600MHz, CL 18-22-22-42

CMW16GX4M2Z3600C18 – default: 2666MHz, CL 18-18-18-43 – XMP: 3600MHz, CL 18-22-22-42

CMW16GX4M2C3600C18 – default: 2133MHz, CL 15-15-15-36 – XMP: 3600MHz, CL 18-19-19-39

 

As you can see there's a slight difference in their JEDEC specs and/or the latency in their XMP configuration. The last one has slightly lower secondary latencies. You're not going to notice any difference outside of synthetic benchmarks, if then. So pick whichever is cheapest

CMW16GX4M2C3200C16 – default: 2133MHz, CL 15-15-15-36 – XMP: 3200MHz, CL 16-18-18-36

 

As I said above, it has a slightly lower transfer speed (3200 MT/s vs 3600 MT/s), but the latency is essentially the same. Latency is measured in clock cycles, so more clock cycles at a higher speed may take as long as less clock cycles at a lower speed. CL16 @ 3200 MT/s translates to 10 nanoseconds. CL 18 @ 3600 MT/s also translates to 10 nanoseconds. So no difference there.

 

You're not going to notice a difference in most games and if you do, we're talking maybe a 5% difference at most.

So just get the cheapest one?

Assuming you prefer using your computer over benchmarking it, then yes. You're not going to actually notice a difference between DDR4-3600 18-19-19-39 and DDR4-3600 18-22-22-42 when sitting at the computer without a synthetic number telling you that one is faster than the other.
