Bali is definitely nicer diving but for weeekend getaways, I prefer LOBs to Tioman (or Anambas) rather than flights to Bali if I need to work Friday and Monday. I get more dives, less cost and much less hassle. Either way, you have a tough taxi ride on Friday evening but that's where the similarities end. With flights, immigration queues, Bali traffic, no-fly times, etc, the LOB trips are just more relaxing. Now if I had a few more days, I'd be happy to go to Bali, Manado, Phuket, etc. And a few more days... wow, I do live in a great place for diving, don't I?
