There's a really poorly designated subclass of woodies in my head that I'd consider it the best in—"classic" wooden coasters or something like that. That bucket includes things like SCBB's Giant Dipper, Kennywood's Jack Rabbit and Thunderbolt, SFA's Wild One, etc.
That said, in the wider field of wooden coasters, I do think it is a bit difficult to imagine Phoenix being deserving of the #1 spot unless these rankings are suddenly taking into account accessibility, charm, etc—aspects that have never seemed to matter in steel coaster rankings.
Disclaimer: My number one wooden coaster fluctuates between Lighting Rod and The Voyage.
