The quality of randomness doesn’t really depend on how old your PC is. With modern enough software (and non-buggy algorithms), there is no meaningful difference between randomness generated on a PC, or with a dedicated TRNG hardware, or with a hardware wallet.
(that is in the general case where you use a hot wallet to make up a recovery seed. the situation is somewhat different in special scenarios like during the boot process)
For the record, Trezor has a TRNG peripheral built into its CPU. And it also adds entropy provided by the host PC.
But the „quality“ of seed is not an interesting metric. There is no ordering of wallets by „how good a seed“ they produce. The measure is either-or: either the seed generated correctly, or it isn’t. The point of a hardware wallet is to keep the seed off your PC, not to make a better one.
