I like Voice.suttacentra.net because the searches show me the connections between suttas. Indeed, the EBTs in my head are organized by search phrase. I have trouble remembering sutta numbers.
Voice also generates downloadable audio playlists for my daily walking meditation. I have found listening more fruitful than reading. Reading is more “skippy and scattered”. Listening requires steady attentiveness.
I like suttacentral.net because it’s very well organized and meticulously planned and executed. It also offers access to D&D.
I also frequent Buddhism Stack Exchange as an exercise in testing right view. It facilitates a Q&A interaction that supports an effective learn-teach-learn strategy of study.
One advantage of AtI over SC is that, being an older site, it supports pretty much any browser. It’s a battle-tested design that has stood the test of time.
AtI’s integration of Suttas and “commentary” in the sense of talks, essays, notes, and the like, also has its advantages. We approach it from a more purely “sutta-only” perspective, but there is definitely something to be said for having modern explanations and reflections at hand.
I cant believe i forgot to put Bhante Anandajoti’s Ancient-Buddhist-texts.net on the list. I love the different formats he makes available. But he is probably the best thing about the site. He is very generous.
I visit frequently (and it was my first web-site where I could read in the early texts) Palikanon (DE). There are also introductory texts; and even if they provided the K.E.Neumann - translations (which are rated as containing errors and/or messes) I like that site much.
Even more, some friendly impulse let the author make a windows-helpfile-format file which accompanies me everywhere I go with my laptop: it allows to be free of internet-connection and also has a nicer GUI than the webpages. (Unfortunately he never updated this and so the website’s updates and extensions are not in that help-file, it’s a pity…)
