Tablet Replacement revisited

The older thread on this topic was archived so let's discuss again...

I have an OG Shield Tablet still used daily. Mostly it does its job but the response lag and short battery life are making me want to wishlist something newer this holiday season. With Black Friday coming and all, and no updates from Nvidia on the tablet horizon, any opinions on current Android tablets would be appreciated.

For me personally, I'd like to be under $300 but any opinions on more expensive models are welcome as I'm sure they may be useful to other readers.
