Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
RollerCoaster Tycoon

Transport Tycoon Deluxe
Industry placement and economy events add slight noise
Transport Tycoon Deluxe leans a little harder on optimization, though the gap is small.
RollerCoaster Tycoon
Park layout, pricing, and coaster stats are solvable systems
Transport Tycoon Deluxe
Signal logic and network throughput are literally an engineering problem
