Look i have used bloomberg for 20 years and Eikon as well. And sadly despite bloomberg being overpriced, inefficient and irresponsive there are no alternatives. Even eikon is a very poor substitute. Because theres nothing there that has all the data feeds. I want a bond price for a company, i want all the quotes, i want the data for inflation, i want to model a swap with 6 or 7 different combinations of curves, etc... and no one is really paying Bloomberg for their crappy news feed (half of which is wrong or badly out of date anyway). Sure theres lots of people who have one as a vanity device (like your friend). For me bloomberg has all the data on what i need reasonably live with a lot of historics and all the major multiple sources. Theres no other data aggregator there that can come close to competing. And they have reasonable modelling tools. Ok if i want a sexier swap or look at a portfolio impact ill probably will end up doing it excell but they can do the quick and dirty a lot better than eikon or any if the tools you mentioned all of which lack the data, the breadth and the customisability.
