Most of the way through watching (well, listening to be honest) to it now.
I will say this for the Tories, they probably have done better work on the economy than Labour could have done within this time period. However, the economy is only part of a government strategy and the rest of their strategy has failed. They have taken the money from the wrong parts of society in order to cushion the impact on their power-base. Unfortunately though, it's a Catch-22 because if they tried to take the money from those who have lots of money then they'll move out of the country, so they have to target those who can't move. The easy target.
Milliband...the wrong brother won, and I think it was the Unions that put him there, and regretted it later when the Tories tore Labour a new one for being in the pockets of the Unions and Labour was forced to go through their membership ties with a fine tooth comb after the debacle in Scotland.
Since this he's really struggled to climb out of the shadow of Blair and Brown (and his brother for that matter), and has found himself unable to put forward a plan to help keep the economy intact without stealing parts from the Conservative economic plans.
I like the idea of Labour taking on some of the monopolist companies, but honestly I don't think that they have the power to do that, and I think that if they got into power they probably would water down the plans or not enact them at all.
Now the interview is coming to a close. I'd say that Milliband did better than Cameron, he was certainly trying to shed his timid panda image and come out fighting. However, he's still vague when it comes to actual facts and figures. That's partly understandable because you don't want to commit to something when you have the risk you might not be able to deliver it, but it's undermining his image when the Tories are putting out their 'Long Term Plan' (TM) and stating what they want to cut and where and by how much.
Honestly though, I will likely end up voting Labour. I voted Lib Dem in the last election, and whilst I'll admit that the economy has recovered partly due to the actions of this government, the sheer betrayals undertaken by Nick Clegg and his general weak-willed attitude. Well, he's done more damage to the Liberal Democrats than any sex scandal ever could.

The Greens are dreamers, and I don't agree with them wanting to scrap Trident, I believe we need a sea based nuclear deterrant as long as the world contains nuclear weapons. The nuclear genie is out of the bottle, and as other nations are advancing technologically and economically they are going to want to develop their own nuclear weapons systems. North Korea has (as primitive as it is) and Iran is likely to do so, and that will mean that Saudi Arabia will probably want to go nuclear next, and so on and so forth.
If we are to make any nuclear cuts it must be done so as part of a global inititive rather than as a selfless act (which comes back to bite us in the arse later).
UKIP...I won't dignify them with a response, the worse possible outcome of this election would be a Tory/UKIP alliance.
And, despite my slim approval of their economic achievements, I just can't agree with the damage that the ConDem alliance has done to the social fabric of this nation. Not that I expect Labour would have done much better, to be honest.
So, it will be Labour I vote for, not that my vote will really matter at all, I live in an area which has been a Conservative safe-seat since the Conservative Party was created, so really I might as well make the ballot form into a paper aeroplane and throw it in the sea, but a) I always believe that if you don't vote you can't complain about it, and b) there's always that sneaking risk of UKIP getting its claws in around here, and if my vote can help slow that down then that's something at least.
