Galaxy Tab S3...a new one is coming out soon. I have two versions of the original Tab S and I really like both of those tablets...screen was gorgeous compared to any iPad when I looked at them side by side. I do a lot of media consumption and they work well for that. Screen resolution on my tablets is 2560x1600, so better than the "retina" screens on the iPad. The newest Tab S versions have a 2048 x 1536 screen (still "retina"), which was a downgrade in res obviously but they were trying to be more like Apple, to their detriment IMO.
Microsoft Surface Pros are also good tablets from what I understand, but quite expensive compared to Android tablets.
