In the traditional amplifier world OP-amps and chips in general are often considered sort of "low end".
Now we're in the Class D forum and the rules have suddenly changed.
Which is better? To use transistors or chips?
When you buy OP-amps and readymade cirquits they are already optimised for performance, is there any reason to use the old school components beside maybe saving a $? I said maybe because the new cirquits aren't so expensive anymore.

Somehow I think IC is always better if specifications for design are good and design is well made. Anyway, I don't have any experience on comparing these two objectively. Some good reasons could be:
- Tighter layout on substrate. This translates to better EMI properties, smaller parasitic components and shorter transmission lines (digital circuits).
- Well tested as no one makes on IC before making sure it works
- Smaller footprint on PCB
- Ease of use --> may be a downside for a hobbyist
