Jcon wasn't saying Attack was better than Sith. He said Attack was better than TPM and Sith was even better than that.
ESB will always be number one for me. Return and Hope are tied for second. The Force Awakens is next. Rogue One I didn't like at first but the more I watched it, the higher it got and I think it places just after TFA. I actually really liked Solo and would put it after RO. Then comes ROTS, TPM and Attack. TLJ...I don't even know where to place this. The acting was really good, but the story and direction were absolutely the worst of all the Star Wars movies. I hate watching the prequels because of the wooden acting, bad direction, crappy script...but the ideas were really on point. Where as with TLJ, the acting was the only good part. The story, ideas and direction were just the worst. And it makes me mad any time I watch it because of how they handled Luke, and that stupid useless casino scene...and the idiotic chase through space. OMG that movie makes me so mad!
Anyway...that's what I like.
