The online translating service ImTranslator is the best overall translator between Spanish and English because it provides translations from four of the leading translation services. It provides translations from PROMT, Microsoft, Google and Babylon.
Microsoft, Google, Babylon and PROMT are four of the leading translation services. Each has its strengths and weaknesses, according to Gerald Erichsen of About Education. In 2013, he compared five of the leading translation services for accuracy. However, translation services are continuously updating and improving their methods. In addition, there is no website that is consistently the most accurate. What ImTranslator does is bring together the leading, most accurate websites to one place to allow the user to choose the translation that is closest to the intended meaning.
