To summarize,
bucket-less pros is more flow
no need to share outlet flow with bottom venturi, which used to fill the bucket, so 10-20% total flow difference for same pump go with bucket/bucket-less.

bucket-less cons is less safety margin
when in track or long right sweep of any kind, if the fuel level is low(say 1/2), the bucket-less setup make the fuel in the tank move away from pump pickup, which results in fuel starvation.

Some of the problems and solutions such as hydramat with bucket-less have been discussed alot in some threads.
