Mine would be like this:

1. BIND: I love the portals, a well implemented mechanic. Bomb sites are well designed and fun. (I still don't understand the need to make Attackers Spawn that long. Just make the Cave being the spawn zone.)
2. BREEZE: CS style. Could be the best designed map, but A site's too complicated, I hope they change some things there. This map looks really good and has good colors. As the latest released map it makes me excited for the upcoming ones.
3. ASCENT: Simple and clean map, but defender sided, still needs some work. This map became a lot better after the constant nerfs to the Operator.
4. SPLIT: Needs plenty of work (The last changes were good tho). Defender sided. Too many angles and too complicated for a tactical shooter map. I put it here because I really like its style and I think the map has a lot of potential.
5. HAVEN: The map's ok and overall balanced. But it plays and looks too boring in my opinion. I understand a lot of people would rank this map way higher.
6. ICEBOX: I'm sorry but garbage map. The sites are a mess (Especially A), the middle is a mess. Literally everyone I play with wants to dodge this map. I hope the devs rework it entirely.
