I introduced Depot at my org a few months ago and I've been very happy with it. Conceptually it's simple: a container builder that starts warm with all your previously built layers right there, same as it would be running local builds. But a lot goes into making it actually run smoothly, and the performance-focused breakdown that shows where steps depend on each other and how much time each is taking is great.
It's clear a ton of care has gone into the product, and I also appreciated you personally jumping onto some of my support tickets when I was just getting things off the ground.
