Last pet snake ever!

[Batch]

First off, many threads similar to this, but none highlighting these three snakes. I've been researching for months (DON'T JUST SAY DO RESEARCH) but I'm just stuck. If I could I would have all of them. My wife, who's not a snake person has allowed me one last pet reptile as a 5 year anniversary gift. Here are my thoughts, but I want yours.

BCI- Have already kept one. Love the handleability, and size but not the activity levels.

Carpet's-Looked after them quite a while ago at my high school pet shop job. Gorgeous snakes with awesome activity levels. Nippyness doesn't bother me, but I am concerned that my wife will be terrified of it if she does see some attitude.

Black headed pythons- Never worked personally with these, but have worked with woma's. Seems to be differing opinions, but they're some of the best looking snakes I have ever seen.

Any other options are recommended, if you have personal experience. However, I've cared for ATB's, GTP's, BRB's, Dumeril's and am not too interested in Macklot's, Olive's or anything too far over 10 feet and under 5.
