I have to say that I started with the PADI log book but, as I had a DC which I could upload from, I ended up going to Subsurface which is what I use now for all my dives.
Can keep a lot more information (can upload photos/video, geotag locations), see the full profiles (including gas consumption if using AI), use it for dive planning and it is multi platform which means that I can finish my dive and upload it to the cloud and instantly see it on all my devices whether they are android, windows or apple. What I also find useful is the ability when filling out commonly used fields such as buddy, weight, exposure protection etc - they have the ability to auto fill so if I have put in 5mm wetsuit before, as soon as I get to 5mm it gives the option to autocomplete. Makes entering the details for a trip (which could have a dozen or more dives)very easy as I can enter them once, then complete the repeated items within them in about a minute (without having to rewrite everything).
If an operator such as an LDS for a course or boat want to see my experience I can simply open the app on my phone (even without a signal- just make sure the latest dives are synced before you go) and get the dives and profiles up that way. Not had any issues with anyone not accepting it yet.
Almost forgot to say, best bit of all - it is free.
