I signed up for both DF and Discogs at the same time when I started cataloguing and caring about my record collection after over a decade apart. I immediately found DF to be an entirely unacceptable website and to this day my head spins when people take such strong pro-DF stances. DF was an objectively poor quality databasing website and I have yet to hear a cogent negative complaint against Discogs but I am listening.
If you're not the only person looking for such extensive cataloguing capabilities, then it sounds like you've noticed a new opportunity. If you can code and database, I'd recommend you give it a go. Since Discogs is for music - I don't think anyone is suggesting it as the solution for your music collection, plus your anime, Viva La Bam DVDs, Bartman comics, and fidget spinner collection. But seriously, if no one is making what you want (and it sounds like you looked), you should think about making it.
This is fascinating to me. It sounds like you don't know how to use the filters built into Discogs despite it is so intuitive and easy. You can filter by different options which should cover nearly anyone's needs, plus choose how many items to show per page (up to 250), and change the page layout between three different views - large covers, text with covers, and text only. Using the filters can get you alphabetical and text only in a matter of seconds. To your complaint about difficulty in putting a collection together in discogs, it is a databasing website and (un)fortunately data quality is important so we're going to have to deal with the extra few seconds in choosing the actual pressing we have and contributing to the database. Seriously, spend a few minutes on the site clicking on things. If you still cringe about it, then learn how to use excel.
