I have found some side-by-side comparisons on a couple of non-partisan websites but they don't totally jive with each other and when I click the source link to see where they get their info, I didn't see all of what they were declaring. I checked Obama's website and he had an easy tax plan to read whereas the McCain website didn't have anything that was a detailed "tax plan". He seems to glom together energy, healthcare, taxes, and new markets under his economic plan. The tax section was a brief 5 points.
Finally, as one of the articles points out, "when comparing taxes at least, it is hard not to conclude that, as historically has been true, Democrats tend to favor small business and Republicans tend to favor big business."
And that's where ideology of the two parties is important to keep in mind. If you believe in a "we society versus a me society" then historically Democrats would follow your ideology more then Republicans. And "if you think that people on a whole can be trusted with lots of power and money," then the Republican ideology of free markets is for you. On our recent financial crisis, "Greenspan was 'shocked' that free markets are flawed and admitted that he had put too much faith in the self-correcting power of free markets and had failed to anticipate the self-destructive power of wanton mortgage lending."
Finally, don't throw the baby out with the bath water. Just because, for example, the de-regulation on derivatives created the mess we are in doesn't mean we need to dump the scales to the other side of too much government regulation.
Abstract from the Tax Policy Center says:
Both John McCain and Barack Obama have proposed tax plans that would substantially increase the national debt over the next ten years, according to a newly updated analysis by the non-partisan Tax Policy Center. Compared to current law, TPC estimates the Obama plan would cut taxes by $2.9 trillion from 2009-2018. McCain would reduce taxes by nearly $4.2 trillion. BUT Obama would give larger tax cuts to low- and moderate-income households and pay some of the cost by raising taxes on high-income taxpayers. In contrast, McCain would cut taxes across the board and give the biggest cuts to the highest-income households.
Fact Check.org I like this site because it's non-partisan.
Here is an article that explains the two tax plans as I understand it

Taxes are important but we need a President who can present American foreign policy and economic policy that respects the diversity of the world. We can't have an angry, heavy-fisted war monger in office because the world won't stand for it and America is not the only one with the power to destroy.
