I'm a fan of the Warblade/Mo9/with Legacy Champion if you can get it, mainly for Warblade's refresh mechanic. Sure, Swordsage has more maneuvers known, but after 11 levels of Mo9 you have already taken the great ones... and the good ones... and are onto the mediocre ones anyway, even factoring that you can take from all schools, not just the ones available to the class you entered with.
Typically, people like to slip in 2 levels of a non-ToB class before taking levels of Crusader or Warblade, which shifts their stance progression to odd levels (when they unlock new maneuver levels) rather than even levels. 3rd level in particular has a lot of good stances, so I'd recommend taking 2 levels of something else before level 4 of Warblade, and considering its Mo9 we are talking about, probably Fighter 2 would be the best bet (for the feats). Fighter also gives you Heavy Armor Prof, which Warblade lacks. Fighter 1/Crusader 1 also works, as it gets you a maneuver from a 6th school which is equivalent to a feat. You could take Monk 2 for the feats, but you would lose 1 BaB, some HP, and Heavy Armor Prof. Might be worth it though for the saves and flurry. My version of this build is Human Crusader 1/Fighter 1/Warblade 5/Mo9 3/Legacy Champion 10.
Swordsage is the intended entry for the class, and 2 levels of monk+unarmed swordsage helps pay for the feats fairly easily (well, assuming he is a
Cobra Strike Monk of the Meditation of War school(OA) for dodge and blind fight) as well as giving you wisdom to AC twice. It would put you one feat ahead, but Adaptive Style is practically a requirement for Swordsage, so its on par with the above build. My version is similar to the above, Monk 2/Swordsage 5/Mo9 3/Legacy Champion 10.
Why Legacy Champion 10 rather than finishing Mo9? Well, A) Its epic ready, which is like a Tech Bonus for builds, but more importantly B) It's actually 13/10 Initiator Level! In addition to extending the awesome maneuver and stance progression of Mo9, Legacy Champion gives you "an increase in effective level as if you had also gained a level in a class" at 8 of its levels, which translates to +8 Initiator Level. But since Legacy Champion is a class that does not grant maneuvers or stances, 1/2 of its class level is added to your initiator level for all classes. Therefore it gives you +13 IL in 10 levels.
As for damage dealing, well, Mo9 is more about utility. Honestly, Warblade 20 (or Warblade 10/Eternal Blade 10) would make for bigger numbers, what with power-attack returns for having full BaB and the massive amounts of powerful feats you could load up on. Mo9 does get Dual Stance earlier, but for limited rounds per day, allowing for Aura of Chaos+Giant's Stance or any other powerful stance, but the feat hit is simply too great for it to be worth it from a raw dps point of view (at least that's like, my opinion).
If you are taking Bloodclaw Master, remember that Greataxe is also a Tiger Claw Weapon (pg42) and that you can make off-hand unarmed strikes (also a tiger claw weapon, ofc) while wielding a two-handed weapon. Obviously not the intended use for the class, but pretty good. As for getting a Strike at the end of a charge, a Use-Activated Item of Celerity that activates when you charge combined with mark of the dauntless might work... And of course don't forget to hit raging mongoose for +4 attacks at the end of your ubercharge.
