For a new version of project 6, it may be better suited. When a new version of the framework is released, you usually test it correctly to make sure that it meets your expectations when it comes to functionality, stability, and compatibility. And, of course, if it’s even worth converting, sometimes the earlier version still has everything you could ask for.
But since you are going from scratch, you have nothing to compare if you choose version 7, since you did not use drupal 6. And, as you said, there is little support or modules for drupal 7, but so you’d be pretty much in the dark until the rest of the community with previous drupal experience catches.
On the other hand, if you feel comfortable, write your own scales and risk that drupal 7 may have one or more problems, then go, this is a more difficult road, but you will get a hat if you make a little effort it will not have deal with conversion later.
But most importantly, I think that you are investigating whether there are any significant differences between drupal 6 and drupal 7. It is very good that most of what you can learn about drupal 6 also applies to drupal 7.
