I am tossing up changing my SU's for ether the
Twin 45 Dcoe Weber
Twin 40 Weber DCOE/DCOM
Twin 40 DHLA Dellorto carbs.
What would be better out of all of these with a pretty wild build A15?

The two brands are equally as good. Also consider Mikuni/Solex PHH -- the favorite of tokyo 1200 owners.

DCOE 40s and DHLA 40s are good for a wild street A15. The larger versions are for a dedicated racing A15, for a powerband above 7000 RPM.

Don't go by the bore size, but by the venturi size. If you buy used, be prepared to change the venturis.

They are all the same for tuning. Not easy -- just like any carburetor.

Choose the venturis first before doing any other tuning.

Mikunis were sold by Nissan Competition for the A-series engine. Here is a picture of mine:
