Just a little update in case it can help.
Like I told you before, I passed DALF C1 back in March and after sending my application with the attestation, it got sent back because they wanted the original diploma. The latter takes forever to be sent; I still have not received it til' now.
I decided to take the TCFQ, and passed it last week. I think it is much easier that the DALF/DELF, and the thing is even if you mess up they would accurately evaluate your level. With the DALF/DELF, you choose a level to be tested on, and you are taking a risk to fail and not have any score.
For TCFQ, for the oral comprehension, the questions from 1 to 16 are pretty straight forward, with first four being just pictures and you having to identify the situation from sentences that you hear. Afterwards, it's all about simples sentences and dialogues corresponding to each other. From questions 17 to 30 the dialogues become more complex, but their an easy trick that I noticed. When you hear the dialogue, do not too much attention to the 'details' of the dialogue, but pay attention to the general idea. From the multiple choice answer, the likely choice is actually the 'general answer', the one referring to the general idea of the dialogue. The test tries to trick you by putting specific words that you may have heard in the other 'wrong' answers.
The oral production was almost the same as DELF/DALF in the sense that you have to talk, but it was surely easier and less formal that DELF/DALF.
Overall, I think it went well, and I would definitely advise you to choose TCFQ over DELF/DALF. It's easier and you get your results quicker.
Hope this helps
