How can I calculate time complexity and compare between given two algorithms?

I want to calculate the time complexity and show by the equation for both algorithms. Also, I need a comparison between the two algorithms to show which one is better and why. Could you help with that? It would be beneficial for me and very much appreciable.

    Algorithm-1
--------------------------
1.for 1 to m
   for 1 to n
	if (some condition)
      do something
	else
	  do something
   end for
  end for
2.for 1 to m
   for 1 to n
    do something
   end for
  end for
3.for 1 to m
	if (some condition)
      do something
  end for
4.do something
5.for 1 to m
   for 1 to m
    if (some condition)
      do something
   end for
  end for
6.for x to y
   for 1 to x
    if (some condition)
      do something
   end for
  end for

Algorithm-2
--------------------------
1.for 1 to m
   for 1 to n
	if (condition)
     do something
	else
	 do something
   end for
   if (condition)
    do something
  end for
2. do something
3.for 1 to m
   for 1 to m
    if (condition)
      do something
	  for 1 to x
	    if (condition)
		  do something
		  break
	  end for
	  if (condition)
		do something
   end for
  end for
