Yeah, I’ve had similar questions, especially during med school when we covered pharmacology in more detail. In general, ibuprofen is great for quick relief—it usually starts working in 30 minutes or so, which is useful if you’re dealing with sudden pain. Naproxen, on the other hand, tends to last longer—up to 12 hours—so it’s better if you’re looking for sustained relief without redosing. For me personally, ibuprofen irritates my stomach more, even with food, so I tend to reach for naproxen when needed. But like you said, effects can vary. I found this resource pretty helpful in laying out the basics and safety info: learn about dna. It’s more of an educational read than a user review thing, but it helped me understand the differences better. Curious to hear what others prefer and why.
