You don't say how much experience with the 44 mag or what you are planning on using them for. If you haven't shot a 44 mag quite a bit, stick with the 44. That's plenty for most people.
I have owned all of the mentioned several times but have traded/sold to get something else and usually end up missing them to much 😆 and when I get the cash I usually look for the same revolver or a different one. I have owned a 500 s&w,460,454 casull, 44mag & the 475 linebaugh. I also currently own a 10mm. I just couldn’t figure out which one to stick with . Primary use is for hiking/hunting /camping
