As for both lots of bass and hearing foot steps and gun sounds you have to compromise, because lots of bass makes it harder to distinguish those important for details higher frequencies.
Old CMSS-3D starting 4:10 has best detail nitpicking, but totally kills bass compared to SBX Pro Studio which balances well between details and bass.
While Sennheiser is known audio name Creative's SBX Pro is better binaural simulation.
But at least Sennheiser avoids Dolby Headphone's echo/bass bloat. (7:15 in that first video)
Though external USB sound cards of Creative aren't equal to what can be gotten from internal cards especially compared to price.
Sound Blaster E-serie is intended as stereo DAC and can show to OS only as two channel device so those can't do actual binaural-simulation from 5.1 surround sound.
Besides some older USB sound cards high end Sound Blaster X7 is full surround capable, though definitely anything but small.

Newer Sound BlasterX G5 supports showing itself as surround sound card to OS.

It just has new BlasterX Acoustical Engine software which might have same algorithms or might not as SBX Pro Studio.
Not enough comparisons to fully tell that.
