I have a Kindle 11th generation and firmware would allow either WB or AB. Is there any reason to prefer one over the other (e.g. is one easier or more idiot proof)?

My main motivation is to keep it from updating to a firmware version that enables hardened DRM while being able to use it normally (i.e. connected to WiFi). Is this use case supported, or is 'stay in Airplane mode' still recommended?

Also is there a way to get the last pre-DRM hardening update .bin (don't remember the number)? This Kindle is currently on 5.18.2.

I've been using a PW4 (5.18.1, presumably no updates in offing) for DRM-removal purposes but downloads and USB transfers and UI interaction are much slower. So I'm exploring JB for the newer one.

I was able to download books on it this morning (turning WiFi off immediately), but then requested content removal via device content page, and turned on WiFi briefly to see if the content would get removed. But when this did not occur after several seconds, I turned WiFi off, and verified partial update file was there.

'It would be nice' if I could preserve it as an option for DRMR.
