I just received a 33C and a Futur yesterday. I had to travel today so I had to do a quick shave. I used the 33C instead of the Futur since I think I'll have to dedicate a little more time to my first shave with the Futur. Anyways, I also have a 23C and while the head is the same on both, I felt that the 33C gave a shave that required more work (as in more passes!). I'm a 2 pass shaver and that usually gets me a DFS. Didn't happen with the 33C! In case anyone is wondering, I got the 33C because I tend to like shorter handles and the 23C handle is really long. I used a Bic blade which is really sharp. Next up I'll be trying a Feather blade to see if it performs better. I also have a Parker 97R which is essentially Parker's version of the Merkur 34C and so far I like the Parker head more. Here is the 33C:
