Reviews are good to learn about each printer features if you don’t like to read. Then, just do a check list and see which machine has the best specs for your needs. At least that’s my approach when buying printers because at the end of the day they’re all extremely similar and capable all things considered. A consideration that may only matter to few is the proprietary/open-source aspect.
Reviews will only emphasize bells and whistles you may not even need. Everyone will comment on their personal experience which will vary with the machine they have and the gap can be huge for the same machine because it’s a piece of hardware/software and some may have flaws despite all the quality checks.
As others said, the fix will be easy. Reinstalling everything should never be something you have to do. In the very worst case scenario, chrooting should solve any situation. Contrary to other OS, even removing system files will not force you to do a fresh install from scratch.
