Historically G-Shock watches have been digital and I suspect that's because it's much easier to build a shock resistant digital watch that has no moving parts. Using digital components also keeps the price down and features can be added with small changes to a chip. On the other hand, look what happens to the price of analog watches as you add complications. As for "why" more people choose digital over analog? Probably because that's mostly what's available from Casio and I'd suspect that Casio builds more digital watches because that's what people buy. I like the G-Steel series except for the size, I can't (won't) wear something that large. If you want an analog/digital "tool" watch and budget isn't a concern, I think the Breitling Aerospace is the best example of the species.
