I wouldn't put actionboo in the same class with good tonkin bamboo of the kind that Howard Hill or Great Northern uses. The actionboo perhaps is more consistent, but it adds a whole bunch more vertical glue joints in the laminations, which tends to stiffen the limbs, reducing their springiness. Good, hand selected bamboo will outperform it in my opinion.
For the same reason, I prefer good hard rock maple over laminated/actionwood maple.
Also, as others have said, all other things being equal, limb width for example, bamboo will be thicker. Physically, it will still be lighter than hardwoods. I also agree that the performance differences are small, and most folks won't be able to decipher them without a chrono.
Whichever you choose will work fine. Good luck.
