So it doesn't matter which one to use, the main thing is to have a good hood?

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.
