Recirculating skimmer better?

ARe recirculating skimmer better or needlewheel? I seen needlewheel combine with recirulating skimmers.

Recirculating skimmers are usually needlewheel skimmers. I've seen some other skimmer types use the recirculating method but normally it's just turbo charging a needlewheel skimmer.
