Optical image stabilization (OIS) is way better in most cases because it works by moving elements inside the lens to correct shake before the image reaches the sensor. That means less noise, better video quality, and you can use slower shutter speeds without that annoying blur. Digital stabilization, on the other hand, just processes the image after it's already captured and basically crops a piece of it to compensate for movement - so you lose resolution and the quality ends up looking artificial. If you're shooting video or taking photos in low light, OIS makes a huge difference.
But there's a catch: optical stabilization is more expensive, and not every phone or camera has it. There are situations where digital stabilization can get by just fine, like in high-resolution videos where you barely notice the loss. And for casual use in good lighting, honestly, both work. The thing is, if you have access to OIS, it's way worth spending the money - the quality is noticeably better, especially in challenging scenarios. Digital stabilization is more of a "better than nothing" situation than an actual solution.
It's not worth confusing the two because they do different things. Optical is way better because it physically moves the lenses to compensate for shake, while digital just crops and processes the image, losing quality and detail. If you have to choose, always go for optical - it costs a bit more but the difference in quality is noticeable, especially in video or in low-light situations.
In practice, optical stabilization makes all the difference when you're filming in poor lighting or with zoom. Digital ends up cropping the image and loses quality, while optical compensates for shake without sacrificing anything. The thing is, if your phone or camera has optical stabilization, you're already at a big advantage - digital on its own is more of an attempt to salvage what didn't work out than a real solution.
When I need stable video in difficult conditions, optical is clearly superior, but I think people are being a bit too harsh on digital. Sure, it crops the image, but in many modern phones and cameras the processing has improved a lot - it's not that disaster it used to be. The thing is: what's your use case? If you're filming with zoom or in low light frequently, go for optical without thinking twice. But if it's just occasional videos or still photography, digital does a decent job and it's way cheaper.

Thanks! I use a lot of zoom and low light a lot, so I'm going with optical. Thanks for the clarity!
Are you filming or taking photos? Because the answer changes a lot depending on what you're trying to do. Those folks are right that optical is theoretically superior, but in real-world practice it's more nuanced than it seems.
True optical stabilization corrects the shake before it hits the sensor, so you don't lose image quality - it's like your phone correcting the movement of your hand while you're filming. Digital does crop, yeah, and in low light you can see that it lost data. But here's the thing: digital stabilization has gotten way better over the last few years. Current phones use heavy processing, artificial intelligence, and can do a decent job even if they're cropping a bit of the image. So if you've got a newer phone or camera, digital isn't the disaster it used to be anymore.
The hack nobody mentioned is combining both. If your device has OIS, turn it on and then leave digital on too - most phones do this by default and it works better together than either one alone. Now, if you can only pick one: optical wins hands down if you're gonna use a lot of zoom or film in low-light environments. If it's basic use, daytime camera stuff, scrolling Instagram, digital solved that ages ago. Also depends on how much you want to spend - good optical lenses get pricey.
Are you talking about a smartphone, mirrorless camera, or action camera? Because the budget changes quite a bit.
Optical is genuinely superior, but it's worth remembering that the difference becomes way less obvious if you're using a tripod or monopod - then digital does the job just fine. The thing is when you're holding your phone or camera in your hand; that's when optical really changes the game, especially for video. If your budget's tight and you don't shoot much video, digital will work, but if you can afford to pay extra for optical, go for it.
