What is Jordan Fish's method?

I enjoyed bmth when he was a member, and like most of Architect's new music, but I don't know anything technical about music production. The most complex terms I know are breakdown and bridge - just for lack of wanting to become more of a perfectionist with my playlists.

It's not a rule that I will like every Jordan Fish song, but I have seen people say that they all sound pretty similar, and don't want to realise why late and then stop appreciating them as much.

I can identify that he makes songs sound more mainstream, and they sound overproduced to some people. What do more knowledgeable listeners pick up on?
