The Bombardier Global 5000 offers a longer range of 9,630 kilometres compared to the Gulfstream G450's 8,056 kilometres, making it more suitable for longer flights. While both jets provide luxurious and customizable interiors, the Global 5000 features a wider cabin, offering greater comfort. Additionally, the Global 5000 has slightly lower operating costs, which can be an advantage for budget-conscious owners and charter clients.
