[HBR] what is the BEST receiver

[rob]

What is the best receiver for listening to HF SSB and morse code (CW) ?
Is direct conversion better than superhet?
Is tube better than transistor?
Is discrete component beter than IC packages that have complete mixers 
and PLL all packed up real neat on a single cheap?
Is SMD better or worse for building receivers?

What I really want to know is what is the absolute   best way to build a 
SWL receiver for 7 mhz to do ham radio morse code at  7.000 to 7.050 mhz .

A brand new SWL radio can cost over $500 .
I don't really want DC to daylight.... all modes... I just want to know 
about morse code reception.
What is the best way to listen to morsecode on 7.040mhz?
I have had Kenwoods, Icoms, HEATH, MFJ and  rockmites, knightsmites and 
small wonder labs DSW40 rigs
so what I want to know is what is supposed to be the best receiver you 
can use for 7 mhz and if you build it, what parts...SMD, IC...or 
tubes... should be best for pulling weak signals out of the air.
