Best Press Release Service?

One of my clients companies does about $7m a year revenue, decently large company. He wants to switch from i-newswire.com to another PR service.

Does anybody have some advice as to which Press Release services would work out best for a legitimate, seo/marketing aggressive company with a strong brand that we cant risk harming? +Rep and Thanks will be showered upon all who give good advice <3

Love you BHW :-*
