OnePlus has been a bit up and down since it merged with Oppo back in 2021. It gained greater access to powerful components and partnerships with brands like Hasselblad, while its software and product lineup took a few steps back before finding its stride again. But now, three generations after the merger, OnePlus' latest flagship phone -- the OnePlus 13 -- feels like a fantastic return to form. In some areas, the company is even pushing the limits of hardware and gadget design in ways that rivals from Samsung and Google aren't. And with a starting price of 900, OnePlus has managed to undercut its closest competitor too, which makes this phone a great choice for anyone who cares more about getting hardware upgrades than fancy new AI tricks.

A6600 has a lot to live up to. First of all, it had to follow the A6500, launched in 2016 with innovative features like 4K 30 fps video, fast 11 fps shooting speeds, in-body stabilization and face- and eye-tracking. For a couple of years, nothing else on the market could touch it. What's more, the A6600 arrived just after Sony's 61-megapixel A7R IV full-frame mirrorless camera -- possibly the best camera I've ever seen. From a competition standpoint, Sony is also under pressure to top Fujifilm's X-T3, which has a higher-resolution sensor, more 4K video features and much better handling than the A6500.
