Since you mentioned the Rockwell... the good thing about that one is that you get to experiment and truly find what you like best. I have the 6c (not the 6s), which was my first DE, and it was a great teacher. I still have it though now I'm playing more with my new acquisitions (Timeless, Blackbird, Lupo), and it changed my initial impressions. I thought I would like mild but in my face the mild plates were almost useless. Plate 4 and up for me. And it's fun to use and to learn about DEs, if you don't mind a bulky head. I don't mind it and I've never had issues reaching under my big nose.
Another key thing is not to be fooled by the gap, that is only one minor factor in aggressiveness as it has been tirelessly discussed here. And technique is also super important. My first shaves with the Timeless 68OC (alleged mild) were brutally uncomfortable compared to my Timeless Slim (alleged violent, aggressive beast). Technique needs to be adjusted from DE to DE.
Whatever you decide, I think you have very good recommendations so far and I love Razorock quality at the very low prices the have.
