The Nokia 5.3 is the successor of the Nokia 5.1 Plus or X5 from 2 years ago and while it may have been delayed, it's still only an incremental upgrade over the Nokia 5.1 Plus, one that is no longer compact, has a better camera with support for GCAM, bigger battery and will get at least, the Android 12 in 2022 or 2023 (whatever the case may be).
Also users haven't reported charging port issues on the Nokia 5.3 like they did on its predecessor, which is a good sign. HMD Global has been consistently releasing smartphones on Android One Program and has perfected a lot of things. The video should help you decide if the Nokia 5.3 is the right budget phone for you buy or not.
I compared photos shot on the Nokia 5.3 default camera with GCAM and GCAM vs iPhone 11 Pro, see screenshots from video below.
