2D platformer? It really depends on what market you want to aim it at - and don't say the platformer market.
If you use B3D + 3rd party stuff, you will be aiming the game at a minimum of 3D accelerated machines running DX7. The 3rd party stuff doesn't work/make any sense in B3D's 2D modes... and B+ is better at them also.
If you use B+, your lowest aim will be any system you choose, with an option of OpenGL (which is faster on most modern systems) or even software rendering (which is good for cards that can't even handle DX)... at the cost of there being no fancy 3D effects. If you want to use a straight 2D mode, this is your best option.
If you use Max, you get all the benefits of the B3D+3rd party option, plus a faster language, plus the fact that it's still being improved upon, plus OpenGL, plus near-instant cross platform compatibility, plus no internal limitations (B+/B3D has some), owing to the open sourced and modular environment.
If B+ is not in the picture at all (ie you want the fancy 3D effects), I'd say Max is the only real option.
