TEMS and QXDM comparison

Hi All,
Anyone have used both TEMS and QXDM tools?
Do you see difference between them?

QXDM has much detailed information!

I think QXDM is more detail at L1/L2 analysis.
And TEMS is more used in Driving Test, L3 analysis.
Am I right?

Yes, QXDM L1/L2 detailed!

Yes QXDM has everything from L1 to L3, and can be used for algorithms Optimisation in bits bytes.

TEMS only limited information, but sufficient for Optimisation.

Both requires license, right?

Yes, both commercial tools.

Thank You.
I just see some analysis QXDM, but never use it.
