Canon XA10 vs Canon HFS21 in Bluefin

[shmuggy]

I have been using a Canon HFS21 in a Bluefin Housing and I am happy with it. I have been considering getting a backup camera and was considering the XA10 but see it is a lot more expensive than an HFS21. Does anyone know what, if anything, would make the XA10 a better choice?

How about getting a HF-G10, it is the same as XA10 inside the housing.

Something to look at for sure, do you know how it might be different from the HFS21?
