There are many different paint manufacturers. At the end of the day it is personal preference which one you choose to use.
Just check whether they are artists or students quality and maybe buy one of two tubes to try.
My personal choices are:-
OIL PAINTS – MICHAEL HARDING – www.michaelharding.co.uk
ACRYLIC PAINTS – GOLDEN PAINTS – www.goldenpaints.com
WATERCOLOURS – WINSOR AND NEWTON – www.winsornewton.com
INKS – J.HERBIN – www.jherbin.com
PENCILS – FABER-CASTELL – www.faber-castell.co.uk
