The table above represents my "first impressions" summary of qualitative differences between ASERT and Grasberg. Some more words below it.
UPDATE: The table below is now slightly out of date as ABC is continuing to modify the Grasberg implementation quite extensively. I will wait for their code to stabilize (or better yet - for them to produce a specification) before I re-do this comparison.
This is based on discussions in various places and a bit of feedback from some (thanks to them!)
I'm putting it out here for general discussion in large part because I did not get see any replies on questions and comments posted by myself and others in the comments section on the G'berg announcement. But I think it is crucial to discuss the pros and cons openly.
My views above are open to discussion with any civil participants in the comments here. And of course if you want to discuss with me on the BCHN Slack I'm more than happy to chat about it. I don't claim my view be "the right one" on each point. Certainly some of it is subjective, but I'm entitled to my subjective opinion :-)
I also don't claim it's a complete picture -- it was just what I came up with and I hope you will add any missing bits in the comments.
BTW, I did not color in the "attempt to compensate for drift" boxes because that's just a requirement that exists in one and not the other, I would not color it subjectively in this overview because that requirement deserves a whole discussion to itself (and much more will be said about it).
I look forward to more quantitative analysis of Grasberg, which I know people are working on.

While this is certainly true for block confirmation time, this may be different for transaction confirmation time because more transactions are issued in longer block intervals. Jonathan Toomim has shown these to differ substantially in case of oscillating block times, with the current DAA having a 1257 seconds average transaction confirmation time, which ASERT reduces to 638 seconds. Grasberg will likely score somewhere in between, but exactly where is hard to tell due to the absence of Grasberg simulations.
