It's mostly full and not completely accurate.
I don't use Qemu so this may be wrong, but I was under the impression Qemu was an emulator unless you used kqemu, and then it lost emulation capability's.

For peripheral hardware, emulators and virtualizers are mostly the same, but that isn't the main reason most people use them, it's about the execution environment, which involves how the CPU is handled. Seeing as you didn't bring up a single full system emulator, I doubt you care more about peripherals.
