I always end back with monodraw. Other apps have too many features and style possibilities that you forget about the content. With monodraw I never get distracted.
However, it still has enough functionality that you can achieve a lot of things.
One of my favorites are the anchors. I have even created a small demo/tutorial: https://tamasruss.com/articles/monodraw-anchors
Slightly ironic how you complain that other apps make you forget about content but fiddling with responsive separators and anchor points in monodraw is totally OK :) neat trick though
Haha, true. However, I think this one is less subjective. I just had to create it once then it works. With design, I always have the urge to change it after a week :D
