Unfortunately, the Android scene doesn't have an overwhelming number of standout tablet devices. If I had to recommend, the Nexus 9 at the right price is still a nice device. The Nvidia Shield has a similar form factor to the Nexus 7 and would be a nice little upgrade as well with the K1 chip. However, Samsung still makes the most premium tablet of the bunch. The Galaxy Tab S2 (albeit last years model) is on sale for $299.99 which is a good deal for how much tablet you get.
