as a humble cishet, i mainly rate how much i like pride flags by how much i want to lick them. (for example, this new lesbian flag looks fucking delectable https://medium.com/@lydiandragon/a-lesbian-flag-for-everyone-cef397b89459 and gets a 10/10.)
this is also why all 'het pride' flags fail because all of them look like they would taste of licorice and sadness. -2/10 would NOT lick.
