Yes it is worth it performance wise, if you can get good RAM with tight timings. Also you need to tighten the timings further yourself. Is it worth the money, not really for the expensive kits which is why you target a cheaper kit and overclock it.

Exampe: 3200Mhz 14-14-14-34 @1.35v
One of the comments, " I have since tinkered with it and so far I can run at 3400Mhz with the CL14 latencies, and even 3600Mhz with slightly looser timings (14, 16, 16,16). "

You can overclock your way to better performance than this kit, if you are ryzen 3000.

Getting CL14 for me at 3800 required 1.5 volts (getting them to boot requires that voltage) but my overall timings were tighter at CL15 @ 1.45volts. You need a balance of good timings and frequency. That way in game you get the best performance because your frame times are reduced.
With Ryzen 3000, all you need to do overclocking wise is get that bad 66ns RAM latency in aida64 down to 63ns @ 3800. You need to be careful with the dram voltage. Some kits have IC's that will die above 1.45volts. You have to be careful, not put stupid amounts of voltage into your RAM.
