Style/Finishing
Polish on Wood

If you like the natural wood colors and grains then polish is the way to go. Polished surface look elegant and give richness to the overall interiors. The polishing material is available in both high-gloss polish and matt-polish. You can choose the polish style based on the rest of the interiors of your home. PU polish on both glossy finish and matt finish has better shine and durability but are expensive when compared to melamine polish. Grains on the wood are a characteristics of the wood and usually expensive wood such as Teak has grains which people prefer so the cost of polish on wood is higher as you would need to purchase expensive wood for grains and then do expensive polish to achieve the shine. 

Paint on Wood

Paint completely overtakes the finishing of the wooden and the grains of the wood are lost. However this is not a bad thing. A lot of times, you want to do paint on the wood as the paint can handle rough exterior weather where as polish gets damaged quickly. Paint can also provide glossy or matt finishes and paint has many options in colors, shades and styles which are not available in polish.  Paint can be done to finish less expensive wood too as the paint would hide the grains of the wood anyway.
