I would go with the consultant's advice whether it's a CS or not, even if you do feel well informed on vaginal breech births.
I am a breech baby (my mother had a vaginal birth) and had my own breech baby by EMCS this year. My mother was booked in for a C section but her consultant, who did lots of scans and had a fair bit of breech experience, thought I was in a good position (well, as good as you can be the wrong way round) and my mum had a 'good pelvis', so thought it would be ok. And I was :)
My own daughter was an undiagnosed breech - they only realised when I had a VE when I went into hospital while in labour. Admittedly, they didn't go into lots of detail about it but when they realised her position from a scan, they said a CS was the safest option. I questioned it, of course, having known that breech births were possible, but wasn't given a choice. However, even if my DD's position was favourable and my pelvis was a good shape (I don't know if these things were the case), his decision could have been based on the level of experience with breech births in his staff, at that hospital etc. I think you need to consider this too, because midwives and doctors etc have far less expertise in this area than they used to, simply because more breech babies are being delivered by CS now.
My EMCS was actually fairly calm and I recovered very well, even if it has taken me longer to recover emotionally, but that's a different story. I know that having a CS can be scary and disppointing, but the safety of your baby has to be paramount.
