Tylenol/acetaminophen is good for fever which NSAIDs won't help. Otherwise, take both and alternate their dosing times for better pain coverage.
A fever is not dangerous within normal parameters, except for being dangerous to the virus and bacteria that threaten the body. Your body runs a fever because it engages in a battle to the death with these microbes.
If you defeat the body's own defenses by lowering the fever, for example if you are a nervous mother who hates her baby's fussing, or if you're hospitalized and the nurses are laser-focused on "number go down" treatments, then you can expect to be ravaged by the contagion for much longer than expected.

You can't just 'vibe medicine' or 'vibe biology' - please don't comment if you don't know what you're talking about.
The vast majority of the time medicine can only ever help with (acute) symptoms and rarely the underlying cause unless it is something like vaccines or antibiotics.
Medicine has side effects because if there was a free lunch to be obtained from medicine, the human body would have synthesized the medicine directly. Hence medicine is always about making tradeoffs.
When it comes to general health, there is always a causal chain of cause -> primary symptom -> secondary symptom -> tertiary symptom -> ... and a lot of medicine tends to work on the secondary or tertiary symptom.
Pain evolved to be an accurate indicator of damage to encourage you to stop ruining your body and not a punishment.
I did a fevered research dive last time I had the flu and came to the conclusion that there wasn't really any good evidence that fever is helpful for flu, and I should have few compunctions about suppressing it. (And that most of the situations where fever is really valuable for are ones where in the modern world you should go to a hospital and in the case of a bacterial infection be given antibiotics)
