I'm hesitant between the first too, mainly for time constraints: the first sync takes a lot time (up to 4 hours) for my library, specially so if it's done via either wireless connection.

Perish the thought of arguing with the author of Calibre! To him my praises and my unending gratitude for creating an tirelessly improving such an excellent, nay, superb tool for e-book library management.
That being said, in my practical experience:
- Doing a search on my library files there seems to be at least as many opf files as e-books
- Every time I update an e-book metadata , the corresponding opf file changes size and date/time
- It remains to be seen if the "Save to file" option is in fact too heavy compared to a simple e-book sync
I'll keep making experiments, I think, until I reach a better solution than my current Calibre Companion implementation.
CC is somewhat quirky but (dated interface and maintenance issues aside) it still works on every device I've ever used, be it smartphone, tablet and/or Android e-ink reader, with various backup/restore instances (with CC own e-books and database backup files) between any and all of said devices.
Much obliged for your attention,
