PPG Bible - paperback or electronic?

I plan to get training in Jan 2026 and thought I would pick up the 7th edition of the PPG Bible and start reading. I can get paperback for around $57 or electronic version for about $35. The electronic version is not PDF - it is some special software you have to install on your computer/phone/tablet to read it.

Just curious is anyone can give pros/cons of either. I obviously understand the different between a book and an ebook, I'm looking for more insight like...
- the software for the electronic version is a pain
- the electronic version has better illustrations and great for quick lookup info at the field
- the paperback version was great for bookmarking and taking notes in
