For portraits and similar studio work, strobes are usually the more flexible choice. They provide much more light, which helps you keep ISO low, use the aperture you want, and freeze motion better—useful for kids, pets, hair movement, and quick expressions. They can also overpower ambient room light, and there’s generally a wider range of flash units and modifiers available. Downsides: you need a trigger, and exposure is set with a flash meter or test shots rather than simple in-camera metering. Some strobes also don’t turn down very far, and startup cost can be higher.

Continuous lights are simpler to understand because what you see is what you get, and your camera meter works normally. They’re also useful if you want to shoot video, and you may be able to start cheaply. But they often have limited power, which can force higher ISO or slower shutter speeds, making motion blur more likely. Traditional continuous lights can run hot, and very bright lights may make subjects uncomfortable or squint.

If your focus is still portraits/headshots/pets, strobes are generally the better long-term studio tool. If you also need video, want the simplest learning curve, or have a very tight budget, continuous lighting can still make sense.
