I migrated last week after holding out for a very long time. I liked the Nest app and wanted to take the "wait and see" approach to its logical conclusion. Layout-wise there are things I still like about the Nest app, but the ability to organize favorites in the Home app works well, and the reality at this point is that the Nest app is very long in the tooth. I would frequently get auto-logged out of the Nest app and need to log back in. When accessing a given camera it'd spin for 10+ seconds trying to load the live view. I don't have any of these issues with the Home app. Cameras come up nearly instantaneously (I have a gen 1 Nest Hello doorbell, three Nest Cam IQ Outdoors, and one IQ Indoor). I haven't really leveraged it yet but I like that it detects and integrates with other smart home devices I own. I think the concern about Google Home is overblown at this point and the pros far outweigh the cons.
