Hi @paulanthony,
I wonder what it is that you are going to launch but let's see what you've got in store for the community. Having said that, it's difficult to determine the best comment but you have given a criteria so it won't be a problem.
The comment with the highest number of upvotes will be the winner. That's pretty straightforward. Thanks for the opportunity.
Waiting for launch of your project as well.
Regards,
Ilyas
