Definitely better than the piano collections version, though both arrangements aim for something different. The piano collections version aims to emulate the feel of the battle (which it does rather poorly because of the stop and start nature of the piece) and this mix is more brooding, less blood pumping and at times even menacing.
I would've like to hear more advanced harmony, but as Noir said, he aimed for Late Romantic rather than total impressionism. One minor gripe (apart from the bench) is that you can hear the dampers slamming on the strings, so that it's possible to hear some thuds in the quieter portions of the mix.
