A Panzer IV is one where I would definitely not use single-piece, soft-plastic tracks  The way the track hangs between the return rollers makes tight tracks look wrong to me.

Friul  Originally Friulmodelissimo when the company was based in Italy, then it changed its name to Friul Model, but I'm not sure anymore if that was before, with or after the move to Hungary.

Most modern vehicles have much larger track links, so less fiddly work, yes. These Panther links are a good size too, Sherman tracks are doable, but I wouldn't want to assemble, say, Universal Carrier workable track unless the links just clip together.
