The M provides a more upright position. This is a matter of preference. If you can, test ride a M and a S and see which one you like more. When I got mine I tried the M and did not like the flex and the position, then I tried the S and immediately knew that this is what I want. It's subjective, give it a try and see which one you like.
6 gears is a good choice. The have three versions for the 6 gears, normal, +8% and -12%. The difference is the size of the chainwheel. You can always get spare parts and change latter. I got the -12% so I can handle steeper hills.
