I can recall a number of outages on us west 1/2 so not sure the argument applies maybe us east 1 failure is just more visible when it happens... the latest incident didn’t impact all of us east 1 - really just people using kensis right?

No one should use us-west-1 unless they have a good reason to: It's more expensive, only two AZs for new customers, frequent capacity issues, and slow to get new services. us-west-2 should almost always be preferred, as it's a flagship region and only a couple light-milliseconds away.

As a user of us-west-2, I've found it to be very reliable. I can only remember a couple minor issues off the top of my head. The region hasn't even made the leaderboard. [1] ;)

Every time us-east-1 goes haywire, I can kick my feet up and relax as the world burns.

Well, yes, but services like SNS and S3 use kinesis, so if you used either of those...
