The main ones I use are below:
This Estwing, mine is an older version, but I've had it about 10 years now from when was working in framing. I use it mostly for demo work or the little bit of framing I have to do when remodeling my house.
This is my go to hammer for everything else, as it is lighter, and is a true 16" which helps for measuring between studs on drywall.
I use this for anything and everything really that I don't want to ding, dent, demolish or pound a nail into. I actually have an older maller with the same double head concept, but it is a cheaper one, and has seen a bit more wear and tear, so I use them interchangeably.
Great for bench work, or finish work, glue ups and dry fitting, etc.
This was a more recent buy, at least I think it is this model, just a couple years older with an orange handle. I use this when hand driving framing nails, as it has the magnetic nail set holder, and a waffle faced head. It is still pretty heavy and is a bit more stout than the estwing.
I have a handful of extras that come in handy when I have help on projects, or when I've brought tools to help others with projects.
