On this shot, there's Hot Wheels, Matchbox, Majorette, Maisto and Norev.
On this country of mine, Mattel doesn't sell Matchbox anymore, since 2008. Majorette miniatures vanished from the shops some years ago, but seems they're getting back to Brazil. Norev is a rare sight, at least where I live.
Hot Wheels and Maisto models are the easiest miniatures you can find on the pegs
I always prefered Matchbox miniatures than HotWheels. But I can't find a Matchbox miniature in here for more than a year. Just HotWheels. :/ It's also hard to find other brands like Majorette or Norev (I only have two Norevs).
There are lots of Maisto diecasts. But they don't look good.
