Without giving any further details regarding your needs or which country you are from, it’s difficult to make an actual advice.
IMHO the Nothing Phone (2a) offers a great package for the price. While it uses more cheaper materials, you won’t notice them anyways if you are using a case. You won’t get wireless charging, which may or may not be a big deal and the Glyph Interface is more simple with just three LED strips on the back. Cameras, performance and display are almost as good as the more expensive Phone (2), I’ve heard the vibration motor on the (2a) is actually better.
The Nothing Phone (2) has recently seen price cuts and is currently also on sale at a few stores here in my country, it offers the most features, performance and a more premium build quality.
The new CMF Phone 1 is the most budget friendly device. If you don’t need wireless charging, NFC, an Always on Display or an ultrawide camera and don’t care about the glyph LEDs or the transparent design, it’s a great phone, especially considering the price.
