I have one device (that I can think of) with 2GB of RAM and I use it when its appropriate for me (I need a portable laptop with disk space as it has that).
When using a device with low RAM (and I consider <5GB to be low RAM) I tend to use the machine differently and avoid multi-tasking unless the apps share resources & none are excessive in RAM use unless I’ve considered before starting the app how it’ll impact performance. I do also tend to use different apps on lower-RAM machines somewhat; but I’m not needing to live with 2GB of RAM thus have more choices than someone who does.
Key with low RAM I feel is to setup an appropriate swap for your usage.
