Closing Recommendation
Both machines are a sensible size for plot work, drainage and small foundations, so choose by how hard the machine must work and who will repair it. Take the JCB 50Z if you need to finish more work in a day to cover your instalment, and if you want the widest dealer and mechanic network around you, which is the safest choice when you own only one machine. Take the Hyundai HX35AZ if you run the machine yourself on lighter jobs and value a compact, easy machine with comfort fitted from day one, which is kinder on a new driver in tight places. So match the machine to your work: JCB 50Z for higher daily output and easy repair, Hyundai HX35AZ for easy handling on lighter jobs.
