If you can get a blue Ambanja from tree candy's bonsai bloodline, they're probably the nicest blues I've ever seen on any animal. Nosey be are more for if you just like a solid color that doesn't change a whole lot or have much added in. Ambanjas are like a tye dye color explosion. You'll get multiple types of blues on the same ambanja rather than a solid blue all aroubd.
Bonsai line also seems to be the only chameleons I've ever seen with real purple and not a red/blue illusion. When my baby basks instead of being brown he's purple.
Anyway as you can see I could not be more excited about my Ambanja, the one in my profile pic is one too!
That all said you cannot go wrong with an ambilobe, they tend to show a lot of color no matter what.
