I like twin boom designs in general, and I like H-tails, but just like H-tails there isn't always a reason to use twin booms. Pusher props and jets and sometimes twins, sure, but for a typical single tractor-engine monoplane, there's not much justification. About the only arguments that I could come up with are:
EDIT: I made a few tweaks to clarify that I am talking about a single tractor engine here.

- Cargo carriage: A pod and twin boom arrangement (like a baby C-119 Flying Boxcar with a single engine on the nose) is one configuration to work if building a mini cargo plane with rear loading.
- Handicapped access: Similarly, a twin boom design might also be a good setup for a light plane that allowed handicapped access by simply rolling up a rear wheelchair ramp.
- Shipping a kit: A twin-boom design could help reduce the size of any one piece of a kit to allow shipping via ordinary mail or parcel services rather than freight.
- Building in a small space: A twin-boom design could also facilitate building in a very small workshop.
