The best drone is the one that fits the mission, laws, support needs and total ownership cost. Buying by camera resolution or advertised range alone usually leads to the wrong aircraft.

The quick answer
Define the job first, then compare sensor, flight time, wind performance, obstacle sensing, controller, repair support and legal requirements. Budget for batteries, storage, charger, case, training and insurance. Verify current official specifications before purchasing.
1. Define the purpose
List the actual outputs: family video, roof photos, mapping, indoor practice, FPV racing or paid production. Each requires a different camera, aircraft and risk profile.
2. Check the rules before choosing weight
Registration, Remote ID, pilot certification and operations over people vary by country and use. In the United States, recreational aircraft under 250 g can avoid registration only under specific conditions; Part 107 aircraft must be registered.
3. Match the camera to the output
Sensor size, lens, dynamic range, bit depth, gimbal movement and codec matter more than a large megapixel number. Confirm RAW photos, vertical capture and log profiles only if the workflow needs them.
4. Evaluate flight performance
- Realistic flight time with a safe landing reserve.
- Wind resistance for the intended location.
- Obstacle sensing coverage and limitations.
- Return-to-home behavior and controller link.
- Battery temperature and operating range.
5. Check the product ecosystem
Look for available batteries, props, repairs, firmware, manuals and current app support. A bargain legacy drone can cost more after two batteries and an unavailable controller cable.
6. Price total ownership
Include at least two spare batteries, charger or hub, memory cards, case, replacement props, Remote ID module if needed, training and insurance.
7. Inspect a used drone
Check serial and ownership status, crash points, gimbal, recording, GPS hover, sensing, battery health and a full controller link. Never accept “powers on” as a flight test.
8. Compare primary evidence
Use current manufacturer specifications and aviation authority guidance. Treat maximum range and flight time as test figures, not guaranteed field performance.
9. Decide with a requirements scorecard
Score each candidate against must-have tasks, support and cost. If two models are close, choose the one with better batteries, documentation and local service.

Jose, thank you so much for your help on how to buy a drone. I agree with your suggestions to only buy a drone if it has at least 20 reviews so that you know they are not manipulated. My younger brother really wants a drone for his birthday next month, so I will be sure to pass along all of your tips to my parents so they can find the best one for him.
