I tried 2 android tablets in the past, galaxy tab 10.1 (1st gen) and the nexus 7 (first gen). They were both pure crap. Since then I've been using mostly an iPad 4th gen and the iPad 2017. The iPad experience is very pleasant. The OS is fast fluid and responsive, especially with the latest swipe gestures. I would definitely recommend the iPad for anyone, including android phone users.
You won't know what you're missing until you used one. Just like a smart watch, I never thought i need one, but once you have one, it's really hard to imagine life without it. At home, I always grab my iPad whenever I wana read Google Play Books, watch youtube videos or watch any downloaded movies (it's super easy to transfer any movie from PC to iPad and watch it on VLC player). It's also more comfortable to read any PDF files (e-magazines, or student's thesis/assignment, journals papers) on the ipad rather than on my laptop. the ipad screen ratio is similar to A4 size and you can basically "flip the page" rather than do vertical scrolling on a landscape monitor). Lastly, when wana view photos together with anyone, its great to view on the iPad using google photos, the 4:3 ratio is perfect since most phone camera capture pic in this 4:3 ratio.
For the above activities, bigger screen is always better. For other activities like instagram, twitter, and facebook, i still prefer to use my phone. For some reason, i can type faster on my phone compared to the iPad despite its smaller keyboard.
Another big benefit of the iPad, it's the perfect travel companion. The battery life can easily give you up to ~8 hours usage and the standby time can last for months. I always bring it for train or plane rides. When I arrive at my destination, I still have almost full battery on my phone for ride hailing apps. No worries at all.
I got my mother an iPad and she never use her laptop ever since. She basically always on her ipad when she's at home. Easy to video call using facetime and iOS is very "old people friendly", which is good because I receive more calls from my mom asking me to solve her phone problem compared to tablet problem.
