I use Tachiyomi for android. It’s the best one imo
Tachiyomi and Mangadex extension (or the scanlators extension if it’s available).
However, most of the time I just download the complete manga from private trackers like bakabt or myanonamouse and side load it locally on Tachiyomi.
I use the j2k fork of tachiyomi on my phone and mostly mangadex on my pc.
what are the advantages of using j2k over tachiyomi?
Runs far better on newer android versions, plus the UI is more polished
New Manga details screen and New Recents page
Dynamic Categories
Automatic background based on manga page

Tachiyomi + MangaReader.to on the web/as an extension
@joucker29 was using mangasoup for apple while it was in beta and it was the best. Got taken off the app store unfortunately. I think the dev is still somewhat trying to get it back on there, there’s updates on r/mangasoup. Other than that using Tachiyomi on my boox leaf2 has been amazing.
