I have not tried TVmaze like he has but I have tried switching my TV shows over to TMDB several times and always ended up back just using TVDB. For most shows, and probably for most people they won’t notice much difference from one scraper to the next. However there is quite a few (mainly older) shows where there is disparities between how TVDB and TMDB lists episodes and specials. Some of this can be mitigated in TMDB with custom lists and parsing NFO’s but some of it can’t such as TV movies which TMDB does not allow to exist as specials on TV shows. Particularly for people who, like myself, have media created well over a decade ago that was named to match up with TVDB it can be a royal PITA to find and fix all the broken media.
