I have only played the Bio so cannot compare. But I think if you prefer a stiffer version, the Bio is the way to go, but if not, that previous model is a bargain on TW.
As far as the overall specs go, its a great allround racket for an all court game and easy to customize. All I have done with mine is add a leather grip to improve feel.
The Max 200G version is very similar in spec, but a bit heavier. If you like the 98 head and 16x19 string pattern, I would recommend the 300 so you can add weight to exactly what you want, just in case want something between the two.
