I was also going to suggest the Gas gas and husaberg options but I assumed you had reasons for knocking them back.
The TMs are definitely tuned, designed and tested to the Nth degree for one thing: Racing.
If racing, be it enduro, motocross or supermoto etc, is the game, You'll be eating a dick finding a machine better suited to the job. Just my 2 bucks worth. They are expensive but I think the top shelf... everything can really pay off in some situations. The enduro models in particular are just wow apparently. MXA thinks the MXers are great too but have some down sides.
But to be really honest, all these bikes are to-die-for machines and one of the biggest concerns when purchasing a brand new bike I think is dealership convenience and support.
If the huskies are coming out with new models soon, then I would wait. Infact I would wait full stop until you've got a full list of 2013 models to choose from. If they get shit reviews but one really shines, or vice versa you get more bang for buck. You never know, maybe the husabergs or gas gas are gonna come with EFI if thats your thing. I doubt it but its a possiblity.
TMKIWI is quite right when he says people are divided on the handling. I guess it really depends on your riding style and physical dimensions who knows
