Which one of these BGA fanouts is better?

Both are the same nominal trace/space, both are skew matched by the time you get to the vertical "home run" area heading towards the connector.

But TDR of the first one wasn't that great. Let's see if the second one is any better when the simulation finishes...

I did read a while back that there's some trickery you can do with picking meander geometries whose pr...

The tracks are also at a consistent distance throughout more of their length which makes me think the SI m...
