1) Wear: oil paint fades and peels over time without care; water-based paint forms a hard yet flexible film that resists fading, though its wear coefficient is slightly lower than oil paint. 2) VOC: water-based paint has ultra-low VOC while oil paint releases several to dozens of times the air standard, causing the strong paint smell; lower VOC is greener, so prefer water-based. 3) Odor: oil paint has a pungent, identifiable smell (some add fragrances to fake it); water-based paint smells mild or none, sometimes a faint fragrance. 4) Application: water-based paint is easy - follow the manual and a brief guide and you can paint yourself; oil paint needs professionals or dedicated training.
