I think the Zalman CNPS-9500 is an awesome looking (and performing) HSF. The only real complaint I've heard about it is the fan cannot be changed. The two liquid coolers are not much better (if any) than air - you don't really see good liquid performance (IMO) until you get to the H100 size operated in push/pull. The CM Hyper 212 EVO is pretty much a 'standard' now.
I'm voting for the CNPS9500 - my $0.02
