As a collector, I like G1 tinsel.
HOWEVER, as a kid I'm pretty sure I would have hated it. Especially if, heaven forbid, it ever got out of control or frizzled.
Even as a collector I don't like G3 tinsel hair (except the series that had Waterfire in it, because that tinsel was more manageable) and I don't like any of the G4 tinsel.
