It depends what Tories get in.
If we end up with the Thatcherite, PFI-loving, paid-up members of the political class goons that Cameron seems to be one of then the country is pretty much fucked.
If it turns out that they instead actually have a clue and stop the wasteful PFI deals, get rid of tax credits and just tax people less, stop the madness of ID Cards, bring back a measure of regulation to the City of London and the financial system generally and they resist the temptation to endlessly reorganize the NHS, the Police, the legal system or indeed any part of Government then we might well be better off.
New Labour does get a lot of deserved bile for its policies but they really should get as much bile for being utterly incompetent, if not corrupt, in the way they bring those policies about.
