The verdict
The Hitachi ZX200 has arguably the smoothest hydraulic feel in the class and is a favourite with experienced operators. The CAT 320 wins on dealer footprint, parts availability, and resale. If you're an owner-operator who values operator comfort, the Hitachi is a real contender. If you're building a hire fleet, the CAT is the safer commercial call.
You're a fleet or hire operator, or you resell every 3-5 years.
You're an owner-operator who spends 8 hours a day in the cab and rates hydraulic finesse.
