Beechcraft King Air 360er vs Embraer Phenom 300e vs Gulfstream G280 vs Gulfstream G400

The Beechcraft King Air 360ER is a twin‑turboprop typically positioned in the utility/light business category. It trades jet speed for short/rough‑field flexibility and lower operating costs, offering roughly 1,500–1,800 nm range (mission dependent) and usually seating about 6–9 passengers. The Embraer Phenom 300E is a light jet aimed at fast regional missions, with about 1,900–2,000 nm range and commonly 6–9 passengers in executive layouts. The Gulfstream G280 sits in the super‑midsize class, delivering substantially more cabin volume and transcontinental capability at roughly 3,600 nm range, typically accommodating about 8–10 passengers. The Gulfstream G400 is a larger long‑range business jet (large‑cabin segment), designed for longer nonstop city pairs than the G280, with published range around 4,200 nm and typical seating about 10–12 passengers (configurable higher). In short, capability scales from 360ER (most flexible, shortest range) to 300E (fast light jet), to G280 (super‑midsize range/cabin), to G400 (largest cabin and longest range of the four).
