It is very hard to compare Berlin with Bangalore, the climate, culture, vibe, etc are very different. I have been to both cities many years ago, they are polar opposites in so many ways. I have family who have studied and worked in Berlin. Their biggest stumbling block was learning German well enough for everyday life. Granted that in tech circles English is widely spoken, but you need good German fluency to handle everyday interactions and the bureaucracy. The laws are very strict, especially with regards to traffic. Knowing English allows you to pick up rudimentary German quickly, but it progressively becomes very difficult. I have studied German to matriculation level and still find it difficult to carry on fluid conversations with native speakers. Reading documents takes a long time, especially unpacking the compound words. Often people make friends among expats of their ethnicity which in turn hampers the longer term integration into German community / society. Your wife might have more difficulty in this area as she would not have a network of contacts built from work colleagues. Echoing @frnkng, you might find the purported quality of life hampered by the limited disposable income.
