Better than the other settlement building DLC, mostly because this one has a small quest line that's worth doing. Being able to build vault related stuff is also pretty neat. However, Vault 88 is huge and they don't give you much build size. I'd say I've only build in about 10% of the area you can and I'm already almost at the half point of the build meter. What the hell. Anyways, it's worth it for the quests and building stuff if you're into that.
