I think you would have to be a expert both in the original languages and the destination languages to answer this question. However, if it is 'Greek textual families' that you are interested in there is a crude method that I have adopted for many years when working with Christians from other nations. I have done a lot of work through interpretation and it is important to chat over with a new interpreter the passages that you intend to use.Because I know the general directions in which other textual families swing away from the Byzantine it is sometimes important to know which 'Greek families' the "Turkish, Burmise, Welsh , French, German, Korean," translation has used. Usually there is not time to do a thorough examination so I have learned to check 3 verses to give myself an idea of the text behind the translation and also the philosophy of the translators as regards 'literal' or 'dynamic' equivalence. (we can explain these terms if anyone needs to know.)Here they are: 1. “Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood.” (Acts 20:28, KJV)“Take heed unto yourselves, and to all the flock, in which the Holy Spirit hath made you bishops, to feed the church of the Lord which he purchased with his own blood.” (Acts 20:28, ASV)In the Byzantine textform this is one of the strongest testimonies to the deity of Christ in the Bible. It speaks of the 'church of God' and immediately goes on to speak of 'his own blood'. According to the KJV then ,the blood of Christ is the blood of God. The ASV/RV/ and most of their children will translate this as 'the church of the Lord'If I find that my interpreter's Bible has 'of the Lord' here I know his version is heavily slanted towards the 'wrong' Greek texts, so I can bear this in mind if I am referring to verses where it might make a difference.2. “And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.” (1Tim. 3:16, KJV)“And without controversy great is the mystery of godliness; He who was manifested in the flesh, Justified in the spirit, Seen of angels, Preached among the nations, Believed on in the world, Received up in glory.”(1Tim. 3:16, ASV)Here again you will see the KJV based on the Byzantine textform has 'God' and it gives another powerful testimony to the deity of Christ, but the ASV/RV has the pronoun 'He' which weakens the testimony to Christ's deity. If I find that my interpreter's Bible has 'He who' or something similar. I know that his translation is still slanted towards the 'wrong' Greek texts (I'm going to get into trouble calling these the 'wrong' texts but I am trying to simplify... believe it or not!) If it has 'the Lord' in Acts 20:28 and 'He' in 1 Tim 3:16, in other words both, I know my interpreter's bible translation is going to be different to mine in some key points. I will need to bear this in mind as I preach.3. This is a little different...“Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.”(Rom. 6:6, KJV)“knowing this, that our old man was crucified with him, that the body of sin might be done away, that so we should no longer be in bondage to sin;”(Rom. 6:6, ASV)(ESV) We know that our old self was crucified with him in order that the body of sin might be brought to nothing, so that we would no longer be enslaved to sin. (MSG) Could it be any clearer? Our old way of life was nailed to the Cross with Christ, a decisive end to that sin-miserable life--no longer at sin's every beck and call! What we believe is this: (NASB) knowing this, that our old self was crucified with Him, in order that our body of sin might be done away with, so that we would no longer be slaves to sin; If my translator's version has anything other than 'our old man' in this verse I know I have another problem on my hands, the philosophy of the translator is one where he thinks I want to know what Paul 'meant'. I don't; I want to know what he 'said'. This means that I will need to watch for the translators doctrinal views.So I can't tell you which mother tongue translation is best in any of these languages, but these verses will give you strong clues as to what kind of translation it is.
