Post processing to 'extreme' levels is a topic where the discussion often splits along generational lines, or along educational lines, or along narrow-minded,traditionalist versus open-minded, new school lines. There are many old fashioned people who loathe anything (and I mean ANYTHING) that deviates from accurate color and accurate color balance, and they will scream "Calibrate your monitor! Your work is awful!" if there happens to be 15cc too much magenta in an image of a baby, and so on. Millenials (born 1983-2001,roughly) often LOVE odd color effects.
This is a lot like asking for opinions on death metal bands, or on what's the best country music artist--in the WRONG place; that is to say, the replies you get will often be very divided, and often derisive. Often useless replies. Of course, if you ask the right people the right question, you can get an answer or two that might be helpful. Again: some people simply can NOT deal with anything that is non-representational, expressionistic, abstract, or 'different' from what they grew up idealizing.
