Seems like a decent price, cheapest it's been on Amazon according to x3 Camel.
CamelCamelCamel.
The 3200MHz C16 version is $160 compared to this one for $149.
although 3200c16 is equivalent to 3600c18 latency wise. But there are other factors:
anything under the sun does 3200c16, but a lot of them won't do 3600c18. Even though it doesn't mean you'll end up with a really good memory IC, but it certainly means you won't end up with some actual shit IC (less commonly compatible, worse temperature tolerance, etc)
3600c18 provides higher bandwidth while maintain same latency.
If you pair with Ryzen CPUs, it'd push the IF frequency higher too => better performance CPU
The only down side of getting this is if you have a locked 12th/13th gen Intel, it will make memory controller fall into Gear2 mode automatically, and tank the performance, unless manually tuned otherwise.
3600Mhz C18
May as well save money and get 3200 C16
