I use iAWriter. I used to use the same one on the Mac, and the iPad counterpart is pretty much identical. I also prefer using Pages over Word, but there is a word on the iPad as well, which does pretty much everything and unless there is a very specific task you that you need, it shouldn’t have a problem.
Then again, the iPadOS does require you to alter certain workflows because of the way it is. I didn’t find that bothersome as I’m an iPadOS enthusiast and I see it as a software brimming with future potential. Overtime, I’ve come to realise that not everyone sees the OS with the same eye, which is fine.
These are at the end of the day tools and whatever feels makes you feel like it’s an extension of your hand, go for that. Could be the Mac, could even be windows.
When it comes to the keyboard, the magic keyboard typing experience is identical to the Bluetooth keyboard—except it lacks the function rows. All of Apple’s lineup in 2021 use the scissor switches. Amen for that.
