If you're not a pro, there's no reason why you still can't switch. Size does matter in terms of whether you bring your gear with you or leave them at home. Panasonic is still making cameras. All of the M43 cameras since around 2014 produce images that are good enough for most people. The lens ecosystem is pretty complete. The size advantage is still there, and if you get a recent model, there's no reason to think that there's anything that will stop any of the cameras from working long term outside of battery availability or camera failure. And in that regard, Olympus (more so than Panasonic) has been using the same batteries for most of their cameras since the beginning of the PEN line.
