Which lizard is best to get an bearded dragon or green iguana?

I Think You Should Go For Bearded Dragon,, I Have One,, Her Names Nessie,, Beardies Eat Veg & Crickets & Locus. They Are Very Active When Out Of Their Cage When They Are In It They Will Sunbathe On A Rock. A Bearded Dragon Will Puff Out Its Beard When It Feels Threatened And Will Hiss But They Don't Have Teeth And Don't Bite.
