Sometime back in the 90s Motorcyclist magazine tested a bunch of helmets.  The DOT only helmets did better than the high end Snell rated helmets.  Even before that back in the 80s I was working on my Mechanical Engineering degree.  I had a lab class where we did helmet testing.  Even back then the professor pointed out some issues with Snell's standards.

Are there some sub standard DOT helmets out there?   Probably but I'm fine with a DOT only helmet although I'd prefer an ECE rating as well.  I couldn't care less about Snell.  I won't pay an extra cent just for the Snell rating.

BTW, Snell never admitted their old standards had some flaws however they did change them after it became helmet makers could no longer meet both Snell and ECE standards at the same time.

Ultimately what is important is that you wear a helmet.  The difference between a cheap helmet and no helmet is much greater than the difference between a cheap helmet and an expensive one.

HERE is the best place to find helmet tests and ratings...

https://sharp.dft.gov.uk/helmets/


Here is the test for my SHOEI QWEST:

https://sharp.dft.gov.uk/helmets/shoei-qwest/

"For every helmet model, we run 32 impact tests on seven helmets across a range of sizes to assess how well each helmet could protect the brain in the event of a crash.

The ratings are based upon the test results of helmets SHARP has independently purchased from retail outlets. This ensure our ratings accurately reflect the safety performance of helmets that are on sale in the UK."

I don't know about the new Snell test, but the original version had a chemical test.
They'd expose the helmets to various chemicals to soften them up, then they'd fail the test.
Rigged results in my opinion.
Bottom line is, any helmet is better than no helmet.

Another reason I don't trust Snell is that they claim that "dwell time" or the length of time one is exposed to the G forces is not important when it is a well known fact that it is. 

Although I don't like Snell it wouldn't keep me from buying a Snell rated helmet since the helmet also meets DOT standards. 

One reason I am not likely to buy a Snell helmet is there are almost no modular helmets that have the Snell rating.  Snell makes it extremely difficult for modular helmet to meet it's standards yet plenty of open face helmets have the Snell rating.  Where's the logic in that?  While a Modular helmet isn't as safe as a full face it certainly offers more protection than an open face helmet.  Even the Shoei Neotec doesn't have a Snell rating.

I have also read that Helmets with internal sun visor won't pass Snell standards.  I don't know how true that is.

My preference is modular helmets with an internal sun visor.  I don't think it is possible to get a Snell rated helmet with those features at this time.

Good information, all!  Nice for people to see well informed alternative opinions.
