I like it all tbh. There's something to be said for putting up walls, joists, and the roughs of a building, but it's also enjoyable to spend some time getting a bit more precise for finish work and making all the various joints fit together seamlessly. And seasonal changes are always a factor too. At the moment I'm doing mostly finish work on the job, being indoors with most things ready to go and the heat turned on. Sadly, it's not going to last for the whole winter, so I'm going to get whatever work will come to me after this comes to an end.

Edit: Realized I didn't answer the second part. For finish work there isn't much of a next guy on that work, but I generally try not to finish nail the ever loving mess out of my trim so that the painters have an easier time with their work.

But for framing.. There are SO many things. The single easiest and most important thing on a wooden building is crowning your lumber when applicable. It doesn't take very long, but it saves so much time and effort from everyone after you, and can extend the life of a floor pretty significantly. It helps walls align more nicely from stud to stud, and just makes things nicer.. The other main thing is a no brainer, but checking everything for plumb, level, and square before locking everything in place is a timesaver in many ways. Other smaller stuff is making sure that all surfaces have nailers for the next layer, which is much easier for a framer to put in than the poor rocker who may only have a screw gun.
