Lane, I agree a good case can be made for Optimal Equivalence. The only caution I would add is that when it comes to context and readability, there is a danger when Bible translations are used in multiple countries. Each cultural context is different. New Zealanders sometimes grumble about the "American English" used in most translations, and that weights and measures are not metric. I say this because a good translation should aim to be culturally neutral as much as practical.
I have found some places though where the CSB is less than Optimal. Eg, I cringe at the translation at 2 Tim 3:16 "All scripture is inspired by God" Is not the word *in*spired theologically problematic? It seems to me the ESV captures this more precisely and incorporates BB Warfield's insights regarding the Inspiration of the scriptures "All scripture is breathed *out* by God".
Lane, can you please expand on this? The NKJV is broadly similar to the ESV in style and translation philosophy so I am curious.
I appreciate the good choice. I am not a fan of the NIV. I try to tell NIV advocates to switch to the CSB

It has the strengths of a readable translation as well as being more accurate than the NIV.
Personally I prefer translations in the Tyndale tradition, hence I use the ESV. I like the CSB in the book of Proverbs. But I think the ESV is more poetical in the Psalms (I groan at the CSB translation of Psalm 23).
All in all I agree with Lane. If one makes use of the KJV, NKJV, NASB, CSB, and ESV they are using solid and reliable Bible translations.
