What tablets ya'll read comics on?
I was on an Ipad Air 2, but last week upgraded to the new Pro 10.5". Comics look *great* on both. They look a little better on the Pro 10.5: that slightly larger screen real estate makes a small but noticeable difference in readability (and there's a bit less glare due to the screen coating). But the normal iPad is just fine for comic reading: If you're looking for a tablet for the main purpose of reading comics it is *not* worth the extra hundreds of dollars to get the Pro, the normal iPad works just fine. I wouldn't go any smaller than the 9.7" screen though, 8" or whatever seems way too cramped.
I also have a Surface Book (MS's high-end laptop-hybrid thing that can turn into a tablet by detaching the keyboard) and that screen is AMAZING for comics at 3000*2000 resolution and 13.5", but I find 13.5" too large to easily hold for reading for any extended period and since the guts of the machine are behind the screen (the keyboard half is only batteries inside), it's also a bit too heavy for extended tablet handholding. My friend has the 12.9" iPad Pro and I found it the same way: slightly too large for everyday "handheld" use.
