Before you read this, read this
You're here to read a comparison between the Pixel 3a and the Pixel 3, which is great. Welcome! But this is an older comparison, written before the Pixel 4 came out in late 2019. We're keeping the content untouched because all the information is still valid, but just in case you were looking for something a bit more relevant, we have a thorough comparison of the Pixel 4 and the Pixel 3a that may be perfect for you.
The Pixel 3a has a lot of the same qualities as the Pixel 3
At first glance, it's easy to see that the Pixel 3a shares a lot of similarities with the Pixel 3. Aside from minor variations in dimensions, these are identical devices from a design point of view. That said, both phones use different materials. The Pixel 3 has a glass back with a coating that gives it a matte finish, whereas the Pixel 3a is made out of polycarbonate (aka plastic).
The Pixel 3a has the best camera of any sub-$400 phone in the market today.
What makes the Pixel 3a truly stand out though is its cameras. Google is offering the same 12.2MP rear camera that you get on the Pixel 3, and the result is that the Pixel 3a blows every other device in this price point out of the water when it comes to image quality. I shot photos extensively with the Pixel 3a XL over a week and was constantly amazed by how close the phone was to the Pixel 3 series in this regard. Essentially, the Pixel 3a is a lightweight version of the Pixel 3 that has the same camera but with a few other features missing.
The Pixel 3a also has solid speakers, but they're both located at the bottom of the device. They deliver an impressive amount of sound, but it's not the same as the front-facing stereo sound that you get with the Pixel 3. That said, the Pixel 3a marks the return of the headphone jack, a welcome move from Google.
You also get a marginally larger 3,000mAh battery on the Pixel 3a, though that leads to notably better battery life when paired with the lower-power processor. The phone has the same capacitive fingerprint sensor as the Pixel 3. Best of all — particularly considering how much the Pixel 3a costs — Google is providing the same three years of guaranteed security and platform updates, making the Pixel 3a that much more enticing.
Elsewhere, you get the same 4GB of RAM and 64GB of storage, but there's no 128GB option on the Pixel 3a. There's also a single camera at the front, and while the selfie quality is almost as good as what you get on the Pixel 3, you miss out on the wide-angle lens option for big groups.

You do get a few extras with the Pixel 3
Although the Pixel 3a offers great value, Google has removed a few features to bring it to that sub-$400 price point. Key among them is wireless charging and water resistance. So if you need those features, you'll want to pick up a Pixel 3 instead. Those features come along with a better-feeling metal-and-glass body compared to the Pixel 3a's (admittedly well-executed) plastic build.
Pixel 3 has wireless charging, water resistance, and better cameras up front.
The Pixel 3a is powered by the Snapdragon 670 processor, and while it holds up to scrutiny for everyday tasks, it isn't quite as powerful as the Snapdragon 845 on the Pixel 3 for heavy-duty gaming. The 845 may be old by 2020 standards, but it's still a very powerful processor compared to the 600 series.
The Pixel 3 also has dual cameras up front that are better than what you get with the Pixel 3a. The primary sensor uses an f/1.8 lens (versus f/2.0), and the phone also has a secondary wide-angle lens that makes a lot of difference when taking group selfies.
Pixel 3a is the better choice for value
If I had to pick a winner of the two, it would have to be the Pixel 3a. The one standout feature on the Pixel series has always been the camera, and the 3a brings that to the mid-range segment. Yes, it doesn't have the same hardware as the Pixel 3, and it's missing out on wireless charging and water resistance, but it excels at the basics. Plus, it has a 3.5mm headphone jack. So if you're looking for a phone for under $400 that has an excellent camera and is great for everyday usage, the Pixel 3a is the obvious choice.
If you need the extra features, then you'll have to pay a little more to get your hands on the Pixel 3. And if you catch a sale, you may even be able to get the Pixel 3 for the same price as the 3a — and at that point, the 3 is a better choice. Just know that you're buying a two-generation old phone, with the Pixel 4 available, and that means it's starting to feel its age in some ways as well.
The best compact mid-range phone of 2019
By retaining the same camera as the Pixel 3, Google basically ensured that the Pixel 3a was the king of the mid-range for a year. Then there's the fact that the Pixel 3a also has three years of software updates, and you see just how good a deal it is for under $400.
Depreciation did its thing, and this is a good buy now too
The Pixel 3 is an exceptional compact phone at its discounted price. It has outstanding cameras both at the front and back, and it includes wireless charging as well as IP68 dust and water resistance in its metal-and-glass body. And it's not much more than the Pixel 3a.
