Closing Recommendation
Both are 20-tonne class machines with GPS and an AC cabin, so choose by ground and by duty. Choose the Komatsu PC210LC-10M0 when the work is mining or heavy earthmoving, when more engine power and a bigger fuel tank keep you working on remote sites, and when a longer warranty lowers your repair risk. Choose the Hyundai R220LS SMART Plus when the soil is soft or wet and lower ground pressure keeps the machine moving, when steady digging force suits general construction, and when your work stays close to dealer support. So match the machine to your work: Komatsu PC210LC-10M0 for mining, power and fuel range, Hyundai R220LS SMART Plus for soft ground and general construction.
