Competitiveness of the hardware is just part of the problem. I had several Samsung devices in the past and at least 2 were Galaxy Tabs. Consistently the long-term support isn't there. My Galaxy Tabs stopped receiving updates, major and minor and I was stuck on an old Android version until I sold the devices, even though the hardware was still very capable. My experience with iPads have been the opposite, the hardware was never a big selling point for the iPads as I didn't buy it for the specs (nor does Apple market by specs mainly). My iPads continue to receive software updates and optimizations. My iPad Air 2 has gone through 7 major generations of iOS (my Galaxy Tabs - 1).
So all this fancy hardware in the new Galaxy Tabs don't sway me. I can expect about 3-4 years in, and the support would diminish and stop. Then I'm stuck with whatever Android version the device last supported unless I want to spend my time to figure out what aftermarket versions work best on this device, which is a waste of my time as I don't enjoy that.
