Walker basically makes an OEM style exhaust. Tight sealing, mid-flow, quite tuned. Whereas Dynomax, Flowmaster, Magnaflow et al. focus on higher flow and more aggressive sound. Just depends on what you're looking for. Personally, I welcome any and all opportunities to upgrade, so I'd skip Walker and go for a performance style exhaust. But that's just me.
