As an SE, I don't see any real new benefits but the SE program is pretty good as it is right now. Although high SQD spenders are seemly ignored after a while.
I don't love having to fight everyone for a preferred seat when I buy at the last moment and I have 3 kids so I don't care about kids but yes, the cafe is my happy quiet place. It has gotten busier and "my" seat has been occupied the last little while I've been there.
The day there is a lineup down the hall for the cafe will be a disappointing day for me
