I would guess you did not first write “CRISPR is an overhyped approach”, then after careful reflection decide, I don’t think that quite captures the intensity, better go with “extremely overhyped”.

The comparison is kind of a category error. One is a DNA editing technique and the others are deliver platforms. I recall the hype mostly being how revolutionary it could be, not comparing it on a timeline to specific technologies that are at different levels of the stack.
