Enable non-free, install firmwares and now they're almost equal in terms of hardware support (which one has newer kernel depends on the year). For support comparable to HWE stack kernels use the kernel from backports repository and now Debian probably has even better hw support because backports kernel is updated every ~3 months following mainline, while Ubuntu follows latest non-LTS Ubuntu kernel, thus every 6 months).
It's been more than a decade these claims aren't true anymore. Please stop repeating the same old myths.
