I am looking to learn some Torah. I like the Steinsaltz version. But i believe there is some controversy. Is this an acceptable or unacceptable version of Torah?

R. Adin Steinsaltz's edition is definitely accepted by the mainstream orthodox and traditional. The controversy you may have heard about, was raised by several haredim & anti-Zionists, so if modernism and Zionism don't bother you, it's highly recommended, and totally fine from a rabbinic orthodox point of view. It's actually better than most haredi editions, which are confusing because they often don't differentiate between midrashim and the literal meaning, and sometimes consciously downplay the importance of the Land of Israel, which is clearly central to anyone who learns the original Hebrew or an unadulterated or unbiased translation. I may also suggest R. Aryeh Kaplan's The Living Torah.
