It's a bit of a learning curve, but with some practice, seems ok. But the joints never look as shiny. And rework can be a bit tricky.
If you keep the solder out of your mouth (wash your hands after working with it, etc.) there is no danger of lead poisoning.  It's a popular misconception that the smoke from soldering contains lead, but it doesn't.  A little fan or other ventilation isn't a bad idea, though.

Fair enough, but any new gear I work on is lead free. And around here, arguing with Health & Safety is a losing bet. Of course, I'm lucky enough to have an employer who's willing to pony up $2500 for a lead free rework station and a fan with a charcoal filter. So there's no lack of tools.....
Is it worth the hassle to keep some lead out of the environment? Debateable for sure.....

What we should remember is that all the lead used in solder originated in the environment in the first place. The problem is that it now accumulates in unwanted places like old battery factories and landfills. Even eliminating lead from solder now won't have much effect for decades. I do wonder if it's really warranted, but then I did play with mercury as a kid...

I can remember when I didn't have clamps or enough hands, I would hold a wire to be soldered with one hand, the soldering iron in the other hand and the solder in my mouth

Mercury is more bio-active than lead in the form of methyl mercury, which accumulates in the food chain rendering predatory fish inedible and ruining sushi among other things. Mercury used in early California gold mining still pollutes the SF bay through runoff from old mines. But it's solder that gets the attention.

On my last project I used some PbSnAg solder, can't remember if it was 2% or 2.5% silver. Either way, just as easy to work with as regular old 63/37. But does anyone know if it actually provides any benefit over non-silver? Is it actually stronger/better bonding/longer lasting, or is that something of a myth?

In theory, it's a little stronger, but the real advantage is when you're soldering to something that contains silver. Back in the stone age, Tektronix used tie points for high impedance point-to-point wiring that were made of ceramic with the notches for the wires being plated on the ceramic substrate with a silver-based material. Every scope came with a little spool of silver-bearing solder that you were to use when soldering to those ceramic tie points. Using non-silver-bearing solder tended to dissolve the silver on the ceramic.

I wouldn't be surprised if these aren't turning up in the high end audio silver plated tube amplifiers or phono preamps because they help drive up the price, but I don't think I'd use them in a guitar amplifier that goes on the road.

I've been using this stuff for a while, mostly because it's very easy and pleasant to work with. It's expensive, but a small roll will last me a long time. I also have some no-clean Kester for PCBs, which still needs to be cleaned.

Considering what Tektronix test equipment went through (and they still work today) I think it’s a fine terminal strip.  When I built my analog(ue) tape repro electronics I used them and I think it’s skookum as frig.

Yes they are.  And even though they are “Audiophile Approved” they seem to work fine.
