It really depends on where you live. Like for my place we get heavy rains quite frequently so for me using stones or tiles is a good option.

I prefer using paint as I can change the color and look every time we get our house painted. Using tiles/ stone is quite an investment compared to paint.

Painting is good for outdoor, if you don't like this color, you can renew it again, it is very convenient!
besides this paint, we also have other product which can use for cladding, it is the full color outdoor panels,very strong waterproof and make the house looks very beautiful!
