Jack, this is a highly personal choice.
If YOU like it, it is worth it.
But first off, be aware you will most likely lose your engine cover. Quella, and probably others,do make a short-stack version that will fit under the screen, though.
Next, pretty much guaranteed you will have to notch your deck lid for the back two stacks. Some do this with a minimal notch cut. The best looking I've seen though was an owner who basically opened up the entire leading edge of the lid about 1 1/2", and then ran the typical black edge-welting all around the new-sized opening. Subtle and looked stock until you looked close.
In LA you really have stable weather and no elevation change. On the other hand, if you didn't have that stability, those are two good reasons to obtain the consistency of EFI.
Personally, the only stack version I would consider is a modern EFI system. If you enjoy tuning, adjusting and climbing into your engine bay, then the others you listed can run just fine with proper attention.
On the other hand, an old school Cleveland and a Holley still just sort of seem to 'fit' in our old school exotics.
