ATT M2 or Karve B OC

I’m wanting a OC cause I don’t have one. So should I get the aluminum ATT M2 or the Karve B OC. I’m open to other suggestions. The razors I use the most are 34c, Gillette flair tip. I got the .68 GC used it one time with a feather any it was a little too much. Thanks for any help in advance.
