Personally, I am a major fan of the Pixel line-up. Not for their hardware, but for their software and camera experience. The only problem is, that the Pixel phones have always been too rich for my blood. My budget falls more in the range of the Xiaomi Redmi K20 (or the Xiaomi Mi 9T for folks outside India). So, I got one and after spending considerable time watching tutorials on YouTube, I installed the Pixel Experience ROM on it. And it has been great. I get to enjoy the Pixel Launcher and other features of the Pixel phones without the need for a bank loan.
It is not very customisable, but I do not mind. I prefer the stock look. But I am very sure that a lot of you out there might prefer something else. And that is the beauty of Android. There does not have to be a single answer. There is a ton of custom ROMs available, all of them offering their own unique set of features that might appeal to you. And one of them is Resurrection Remix. It is a ROM based on LineageOS, SlimRoms, Omni, and the original Remix ROM builds. It provides a combination of performance and customisation. It aims to provide the latest features.
And if you are a Poco F1 user, you will be pleased to know that Resurrection Remix is now available for the device. A few things you must keep in mind are that it does not include firmware and GApps (Open GApps recommended), so you will have to flash them separately. This is also the first build, so it might not have all the features. If you have a problem with that, you will want to hold off for some time.
