I've had some experience with Poco smartphones, and they indeed offer great bang for your buck. If you're focused on camera quality, battery life, and gaming performance, the Poco F4 GT might be a good fit. It's equipped with a Snapdragon 8 Gen 1 processor, which handles gaming quite well, and it has a decent battery life with a 4700 mAh battery plus fast charging capabilities. The camera quality is solid for its price category, though it might not match flagship-level performance in low-light conditions.
Another option could be the Poco X4 Pro. It offers a good balance between performance and affordability, with a large 5000 mAh battery and a respectable 108 MP main camera that's surprisingly capable.
As for drawbacks, some users have reported that the UI can have occasional bugs or slowdowns, given it's based on MIUI, which might require some getting used to. Also, software updates on Poco phones may not be as frequent or fast as on some other brands. Overall, they’re robust devices for their price, but it’s good to factor in these considerations.
