I voted for the third option. Personally, I don't think we'd be better off under Tory rule - Liberal is hardly a viable choice and without a drastic reform they're going to remain in 3rd place.
Has there ever actually been a government that works for everyone? I suspect not. They all promise the earth, fail to deliver and get supplanted after a few terms and the cycle continues; rinse and repeat.
I'd prefer a solution where the best people and policies were taken from all participants, not a single party, debate with the aim of putting the best/most workable/suitable solutions into practice. Much in the same manner cross-party talks work for debating subjects beyond the scope of a single party. Get the best person/people for the job, and not rely on someone from your own party when there might be someone more capable on another. We don't operate like that with our work so why should it be this way with something far more impacting and important?
The way it is, it's reminicient of a schoolyard - each gang out to try and beat the other up. Reforms/policies take far too long to be implemented - often requiring multiple terms before they're put into practice. Before a term is up, the governing party is concentrating all efforts to win the next one with back-stabbing and one-upmanship, leaving those reforms/policies unfinished. They're a waste of tax-payers money.
Party politics is unpalletable at least not in this flavour.
