Leaded is easier to solder with, lead-free is less bad for you, but inhaling any fumes from burning stuff isn’t good for you, so use an extractor/filter no matter what.
Good advice, although I feel it's important to point out that the fumes from leaded solder don't actually contain lead. They're the same as with lead-free solder: they come from the flux.
I'm a fan of leaded solder. The lead risk can be mitigated by ensuring that after you handle the solder, you don't touch any mucous membranes, cuts, eyes, or anything you're going to put in your mouth until you've thoroughly washed your hands (or removed your gloves, if you're a glove person).
Leaded solder's real downside is environmental: odds are, what you've made will eventually end up in a landfill, where the lead will leach out and potentially contaminate the local environment.
We have no evidence that the lead in solder makes its way into the body of the person doing the soldering (and we've been at this for quite some time!). The concerns about lead in solder are due to the environmental hazards of electronics waste, and the hazards associated with mining and smelting lead.
The choice of flux used is probably more important. Aggressive fluxes are easier to solder with, but leave behind a acid residue which can be problematic for electronic circuits. Fluxes preferred for electronic applications are the least acid, but not as easy to to get the liquid solder to bond.
Personally, I learned on lead-free solder and the rosin core is almost always enough flux for me aside from rework. Always use an extractor/filter either way.

So it doesn't matter which one to use, the main thing is to have a good hood?
No, the main thing is to have a good head!
[Now we're trying to sell "soldering hoods" on HN?!]
Use common sense:
- Solder in an area with constant air flow,
- Keep some space around your work so the fumes move away,
- Don't snort solder OR flux!8-))
Use a good hood/ventilatation system, and lead free solder.

Lead-free. Lead isn't worth it, especially if you're doing this at home.
