Wow, those look impressive.  Almost "smoke thick" like.

gastar, just a thought after checking out your tgd, you do set cloud acceleration cache to 'none' when you're going final, don't you?
perfection is not when there's nothing more to add, it's reached when nothing more can be left out

Hm.... I had create this file with the version 1.8.64.0 and the option was not available at this time. I haven't tested...
Has someone more information about this? Improve the cache only the rendertime or the qualitiy or both?

I find the quality setting to be easier to deal with than cloud samples because this number of samples for a given quality setting will vary according to other settings in the cloud fractal. This fits in partly with what Oshyan said in his first reply about excessive noise in the cloud's input function.  I usually start by setting the quality to 1 and if the resulting number of samples is excessively high then I tweak the cloud fractal's contrast and roughness settings.

AA is another setting that hasn't appeared in this thread yet. This will also have an impact on the cloud's density fractal.
