Arches sucks water like nobody's business. I might try it again with liquid acrylics, but for watercolour, I don't get good results with it. I swear by Montval.

Do you mean the paper or the board? The boards seem not to be the same as their paper equivalents within one branch, which makes it more complicate to find the best ground for one's work.
here is a review by Paul Jackson of the Montval and Arches boards compared to the papers.

I think oils is little bit hard and annoying to work with,especially for beginners.But watercolors can be also very annoying and needs a lot of vigilance.

I think oils are a perfect medium to paint with - even for beginners - because you have time to paint around until the result suits you, if not you can brush away the colour easily and start again. Watercolours are more difficult because you always have to know exactly what you're doing and corrections are nearly impossible. That's why I have the greatest respect of artists using them.
