Azoto Tri Race Gel Saddle vs. San Selle Genuine Gel

I just b ought a used bike for training and need to get a different saddle. Has anyone used both the
Selle San Marco Azoto Tri Race Gel Saddle and the San Selle Genuine Gel? Which do you prefer? I
currenty ride on the latter and it is OK, but would like to try the Azoto.

Thanks for any comments.
