Agreed. I wouldn't buy any 1 GB iPad in 2019. And I definitely wouldn't buy one with an A6X in it. Here are the relative Geekbench scores:

For the record, I own:
iPad 2: A5 - GB score 600 (I owned this until 2 months ago when I gave it away.)
iPad Air 2: A8X - GB score 4550
iPhone SE: A9 - GB score 4550
iPhone 7 Plus: A10 - GB score 6000
iPad Pro 10.5": A10X - GB score 9600
Given my experience with that range of devices, my recommended minimum is 2 GB RAM with a score of 4000 or better, which means iPad 5th generation (A9, 2 GB RAM) or else iPad Air 2 (A8X, 2 GB RAM). The iPad 4 (A6X, 1 GB RAM) has a score of just about 1/3rd of that, which means it would be quite slow for surfing. However, the best bang for the buck right now is the iPad 6th generation 32 GB (A10, 2 GB RAM), at just $250.
