I think either is fine. To be honest, for most people starting off on their PPL I would recommend a small private logbook. The reason for this is that they do tend to get tatty and a bit dog eared over time. Once one is filled ( and that can take some years) it can for the most part, be filed away.
I fly about 600 - 650 hours a year and the commercial logbooks I use (CAA CAP 407) take about 10 years a piece, to complete. With everyday use and residing in a high traffic flight bag, they usually need laminating at around year 6, to stop them falling apart.
