English Language Debian OS for the 2B

Is it possible to get clarification about whether an English language version of Debian is available for the 2B.

Additionally could the following be answered.

  1. Is the 4GB version of the 2B likely to be available on Ali Express, if so when.
  2. How much faster is the 2B 4GB than the 1B 4GB for routing tasks, web browsing, text editing and programing in Python please.
