I've read from only two pdf versions of the translated upanishads, one of the principal upanishads and a couple other by easwaran that ive read many times and one of all 108 upanishads plus a couple others ive read just once. ive realized though reading a couple other versions of the upanishads online that easwarans translations are geared toward beauty much more than accuracy, and I want a beautiful scholarly version. his translation of the bhagavad gita was good enough compared to the four or five other versions of the bhagavad gita ive read from but his upanishad translations are really not great. I need to reread all the principal upanishads at least tbh. ive reread all my favorites already when looking at the original sanskrit word for word online but im gonna stop using his translation as my go to for sure with the other upanishads.
