It really depends on your specific workflow and how well the apps you need have been adapted to iPadOS. I second the advice to just forget the laptop and force yourself to use the ipad for everything until you can't do something. A very important point is that A LOT of the stuff you need can be done with the iPad, just only not in the way you are used to. You will need to set aside some time to explore, experiment and find out alternative ways (which might not be slower in the end, but it takes time to learn and refine).
I am a designer, so I'm bound to macOS for a lot of pro apps. I have an iPad pro because I need it for sketching, and besides that it was seldom used.
A few months ago I got a keyboard / trackpad combo and along with Stage Manager I have to say it expanded the range of stuff that I now can do, and in some cases prefer to do with the iPad.
Stage Manager is still in its infancy (buggy and sometimes weird) and need some time to get used to, but working with windows lets you simply do more in a way you're more used to.
In terms of pure ergonomics the lack of personalization of many trackpad gestures that I'm used on the macbook (like three fingers drag), is a bit annoying (and painful after some time), but YMMV.
