it's very hard to stay excited for a month after just 1 chapter of AOT, it's a cool manga and all but it's not really at the top or anything
I am guessing now that the anime is over and the new fans no longer get 20 chapters to read in one bulk the popularity will plummet
it's not the best art for me but in the published volumes it looks quite good
it's a very simple story and a lot of it's success is due to blood, gore, deaths, desperation, ... which is just fanservice and ofc the anime
but to your question, yes I do like it, it's not in my top manga but it's good
