I suppose they both would NOT work equally.  Is there much besides old USN receivers (like the RAK, RBA, SRR-11, WRR-3, BRR-3, etc.) that will reach down to the *high* end of the VLF band of 30 kHz?  :-)

(AN/BRR-3 receivers with a TOTAL frequency coverage of 10 to 30 kHz were the most important radios on my ballistic missile submarine more than 40 years ago.   We had no transmitters for VLF, but TACAMO aircraft did.)
