For Naruto usually nb, for other manga sometimes mangapanda and on pc(sometimes on mobile too) whichever lets me load whole chapter in one webpage instead of individual chapter pages(I remember mangasee or something).
Mangabase or the original site like Line webtoon for Noblesse and some other webtoons etc. MB because it's handy and I like the reader and can switch to forums if I want. Mangareader, *********** for the stuff which is not at MB/NB. Botato is good but not that handy somehow.
The one that comes out first - Mangapanda. I only read *********** when I feel it has done a horrible job at translating. Though, I get to read VIZ's scans too since I'm subscribed to WSJ (but that comes out later on the following Monday/Tuesday).
