Wrong section to post this thread in.
Is it legal? Not really.
Are they ok to use? It depends really on the cpu and motherboard. For example regarding with the Intel 6th gen Skylake ES.
In order to run the Skylake ES chips, you need to inject the microcodes into the bios or find an already pre-made modded bios. Keep in mind a lot of these bios are using the older bios versions which allows BLCK overclocking since the few skylake ES chips have a low multiplier and thus a clock speed of 2.0 - 2.2GHz.
Side-note: Early ES chips such as an i5 version (I forgot the code for it) has its IGP and PCI 3.0 express disable. You will be limited to PCI 2.0 express.
One big issue is that when Intel caught wind of people using BLCK to overclock non-K chips, Intel forced every motherboard manufacturer to pull the plug on that. ASUS for example won't let you downgrade the bios where BLCK is possible. Just about every pre-made modded bios for skylake ES chips are using the older bios (for BLCK), meaning you won't be able to downgrade to the stock or modded bios. ASUS went to quite a lot of lengths to prevent user from downgrade-flashing it. The only way is to do a hard flash with a special device or just buy a bios chip off of ebay and ask the seller to flash it with an older bios (BLCK days) or provide the modded bios.
Keep in mind, not every board manufacturer uses drop in bios chip like ASUS. Some are solder on.
Experience will vary for different ES chips so it is hard to really give an "overall" experience. It is almost a case by case basis.
Most of the ES chips that are very close to the final production version with proper clockspeeds are almost as much as a regular retail cpu version. So no point in getting those.
Is it worth it? It really depends on the cpu itself and the roadbumps that comes with it. My ES skylake i7 barely could overclock from 2.2GHz to 2.6GHz. I was better off with a used i5 skylake or going with Ryzen in the end.

Be careful with the generation of ES chip. There are different levels of ES production and you want to find as close to retail as possible. Typically QS model numbers. For example: intel QK3E = E5-2695 v4 and is one of the last ES/QS models if not the last and therefore is identical to the production model.
Also, I don't advise buying from sellers in China/Japan etc. Typically they sell the early models that have either features disabled, or have higher failure rates.
I've got quite a few QS / Final revision models around my place and all have been rock solid and stable.

You should ask that question in the Distributed Computing sub forum. Lots of us use ES chips for our crunching power.
I have a few ES chips in my farm. Right now I have two 14c CPUs that I have been searching for a motherboard to use them on. I have an ES V3 CPU in one of my rigs crunching away on an X99 board. It's a 10c/20t CPU and hasn't given me any issues in the 3 years I've had it.
I had 4 ES Opteron CPUs in a 4P board that gave me no trouble for a couple years, until the board went bad. Don't think it has anything to do with them being ES CPUs.

Doesn't have anything to do with snow. Not a thing.

That 4P still works.
