Thank you both for the enlightenment. In my research, KOReader is what I need to install if I want to read imported PDF's that I consider "undeniable, must-reads without an Epub variant".
Unfortunately, some have a text layer, others are comprised of fuzzy image scans, while many have unorthodox column structuring.
Based on your advice, I should do the following?
1. Install KSM8/KOReader
2. Run each PDF through Bliss
3. Import PDF's to Calibre
4. Load PDF's to device
5. Enjoy better reading experience
6. Look for KOReader to break when Kobo OTA updates occur
7. Update KOReader manually
Is that about right?
I'm having a helluva time trying to figure out the best approach to installing KOReader. Are the instructions/links the same in 2017 for Aura (original) as they were in 2013, 2015, etc?
Do I follow the first post in this thread only?

There seems conflicting information regarding installation if one looks hard enough...
