I don't think so.
If timing were that critical to people we'd all be using sync cords. And we're not, so I guess that it doesn't matter in most practical uses.
"Fake manual" is a term you have coined, apparently to disparage Cactus products because you favour a product from a different manufacturer. The Cactus triggers allow you to dial in the power and it works. Nothing fake about that.
This also brings up an important question: since you have access to prototype Acon products then what is your relationship with Acon? If you have an undisclosed relationship with the manufacturer then skewing a review to favour them at the expense of a competitor is ethically dubious.
No TTL is something I could not care less about. For me TTL is like using the camera in 'P' mode and hoping that you're going to get a great shot. You'll likely get an average or acceptable shot, but rarely a great shot in 'P' mode. TTL is the same. I want to control my lighting, so manual is the way to go for me. And I always shoot in 'M' mode as well (except 'X' for flash), so I like to have full creative control. If I was desperate for TTL I'd consider the Acon or just use something like my Vello cord, but it really is a non-issue to me.
In your summation you've picked on really minor shortcomings of the other products, but failed to address that fact that the Acon has a next-to-unusable user interface (the morse code analogy was spot on), and from all the threads here I could add: seemingly terrible customer service, no readily-available documentation that English-speaking people can understand, and a cumbersome and error-prone firmware update process.
