Its better that 11.1.2?

I'm not sure why you think people are playing on 10.3.

As per the rules, runs are expected to be done in the latest version available that is within the range of allowed versions of a given category.

So today, people should generally play in 11.1.2 or 11.1.1 in most categories.

For "Tutorial% 10.3.1+", the range started at 10.3.1 because a breaking change happened in this version, but if you want to submit a run today in this category, you should play in 11.1.2 (android) or 11.1.1 (iOS or Switch), and not in 10.3.
