Can I just say something? Now that voting is out, please THINK about how you're rating maps! It bothers me to no end when people just give all maps multiple 8's, 9's, and 10's. If you're saying each map is perfect, you need to go play them again. No map here is perfect. The below is just my opinion, my suggestion, take it with a grain of salt or don't read it.
If you give Gameplay a 10/10, you are saying that the map is nearly flawless. That means that on all maps, the spawn times are perfectly set so that fighting happens in the yards before points.
A bunch of people wanted to vote by how much fun they had on a map. If a map is not balanced, it is usually not very much fun. If you get frustrated whenever you're BLU, it's not balanced. Don't give Balance a 9/10. Don't use Feedback's win ratio system as the only way of rating balance. Balance includes item pickups, don't forget that.
It is very difficult for a map to get a perfect score in aesthetics. Black props because of lighting issues? It isn't perfect. If a map has alpha textures on one part, you don't give it a 9 :/ Displacements look like they're made out of clay or the polar opposite? Rate accordingly.
Performance. Don't do what I did last year where fps ranges were how you rated the map. It's a contributing factor, but put into account the size of the .bsp and how much custom content is in it, compare it to popular custom-content filled (or stock-content filled) maps and see how their sizes compare.
Technical. Most maps have PLENTY of clipping errors, many are easily exploitable, and I know this. Not to be vain or anything, but no map should really have a perfect 10/10 for Technical. Not even Zig, which was checked by multiple people. But don't forget about any odd spawns. There's a command for that, use it.
