In Europe lead free solder is the standard since many (10+) years, you can't get leaded solder as an option to buy.
It seems to be due to a EU regulation that became active March 1 2018 here in Sweden, it's no longer legal to sell metal alloys containing more than 0.3% (!) lead to individuals [1].
I had no idea, thanks!

For what I remember, the lead free had a higher melting temperature. At least back in the days.
Took one week to get used to.
That stuff will last me for a few years. However, once it's used up, I guess I'll try switching to lead-free as well.
Just a few months ago I bought my first soldering iron. Not only was the little bit solder included with the iron of the Sn60Pb40 variety but also almost all of the solder products on the shelves at my local "Bauhaus" (a home improvement market chain).
For anyone that cares: brand of iron and solder was "Rothenberger Industrial". Relatively cheap but looked like a good and sturdy tool which from my yet limited hobbyist experience it seems to be.
