Android Tablet (at least for the Galaxy Tabs) has actually improved tremendously. Hell the Galaxy Tabs are the only worthy iPad alternative.
You know what Android Tablet has that iPadOS doesn't? A tablet Instagram app. A desktop mode that isn't garbage. Oh, AND A CALCULATOR APP
Meanwhile, on my iPad...
1) I have been using notability to teach in the classroom since 2012. 10+ years later, and notability, goodreader or PDF Expert still have not come to android.
2) Tweetbot and Apollo were great to browse social media with while they lasted. Together with Overcast (for podcasts), Ivory (for Mastodon), Lumafusion (video editing), 1password, Spark (email client), Fantastical, Mindnode (mind mapping), Things (task manager) as well as games like Battleheart Legacy, Slay the Spire and Grimvalor (which came to iOS way before android).
3) Calculator app - so long as you are willing to pay, I had Soulver, Tydlig (now discontinued sadly) and Pcalc.
4) We did have a tablet Instagram app (a third party one called Fastfeed), which sadly, lasted only a while before Instagram yanked access. 😕
I imagine I would be both lost and irritated were I to switch to an android tablet and find that so many of the apps I have come to love and rely on weren't available, and I had to settle for alternatives that didn't work as well. If you are at all concerned with the quality of apps, where people spend 90% of their phone time using, then Android is a garbage fire overall.
There is just no contest here.
