I prefer the Broadway recording. The London OCR sounds too much like a demo recording of Les Miz; the instrumentation and songs changed significantly after the show crossed the Atlantic. Plus, I don't really like LuPone's Fantine.
The Broadway recording is better produced and doesn't lumber along like the London one. However, the downside is that it doesn't feature Michael Ball.
The symphonic recording is good because it's the most complete (although, after the 10th anniversary changes to the show, it's not longer
that complete), but Colm Wilkinson is still the definitive Valjean for me, and to not have him on the recording really taints it.
But the best English recording of Les Miz is still the 10th anniversary concert album. A true dream cast (everyone from Colm and Lea Salonga to Michael Ball and Maguire), a phenomenally large orchestra, a "fuller" performance than on the Broadway OCR, and finally the energy of a live audience.
