Looks like opinion is mixed. In the USA, Jepp rules, and that's been a problem. A monopoltic provider of a service usually means lack of inovation, lack of features that the consumer requests/desires, high prices, etc, etc. Jepp was late to embrace the digital world, when it did offer a product, it was just a copy of their paper product. I experienced LIDO around 2000, transition to electronic was happening and LIDO was leading it. My employer moved back to Jeppesen (of course, after we all finally got used it) and although it was now digital, it still had some catching up to do. When Jeppesen (Boeing) bought Foreflight we saw a rapid improvement is some features Jeppesen had lagged providing. Still got the basic Jepp plate, just like in 1970, at least the ground charts are improving. I think the industry and users (pilots) would be much better off with a true competitor to Jepp, at least in the USA.
