Hello,
Which iPad is it you currently have? Apple offer several models. The iPad mini might be a good choice.
Build quality on these appears to be about the same as it’s always been - certainly one of the top tablet manufacturers out there. If you’re ‘stuck’ in the Apple ecosystem it makes sense to stay within it - if you go Android you may need to repurchase apps, as unless they are subscription based you may not be able to transfer the purchase.
Also worth considering whether there’s any less commonly used apps that you rely on - things such as BBC news, Netflix can be found on both platforms but if you use something a bit more specialist on a regular basis you may find it missing on Android.
