Contrarily I wish people used 'Nx times' more often, especially for 10x in place of 'an order of magnitude'. It's more welcoming and less pretentious.

I'm not sure about using 10x in place of 'an order of magnitude'. An order of magnitude conveys an approximation, whereas 10x is precise.

10x is literally the difference of an order of magnitude.

  An order of magnitude is an exponential change of plus or minus 1 in the
  value of a quantity or unit. The term is generally used in conjunction with
  power-of-10 scientific notation.

  Order of magnitude is used to make the size of numbers and measurements of
  things more intuitive and understandable. It is generally used to provide
  approximate comparisons between two numbers. For example, if the
  circumference of the Sun is compared with the circumference of the Earth,
  the Sun's circumference would be described as many orders of magnitude
  larger than the Earth's. [1]


  An order of magnitude is an approximation of the logarithm of a value relative to some
  contextually understood reference value, usually 10, interpreted as the base of the
  logarithm and the representative of values of magnitude one. [2]

To a mathematician the 0 signals the author intends less precision, but this is not colloquial use
