Which is better for a stock 2004-2010 Toyota Sienna HID setup?

The OSRAM Xenarc Original. Its 4150K color matches the factory look and it is a direct OEM-quality replacement. The Morimoto works too but runs whiter at 5000K.

Morimoto rates the XB at 2500 hours and says it holds 83% of intensity after 200 hours. OSRAM does not publish a life figure for the Xenarc Original, so there is no direct number to compare.

Is the Morimoto worth the extra 45 cents?

Yes if you need a pair or run 55W ballasts, since the Morimoto box has two bulbs and the OSRAM listing is one bulb. If you only need one stock-color bulb, the OSRAM is the cheaper pick.

Can I run the Morimoto XB on a 55W ballast?

Yes. Morimoto lists the XB as compatible with both 35W and 55W ballasts. The OSRAM Xenarc Original is rated for 35W only.

Will either bulb cause errors or flicker?

Both are standard 35W D2R bulbs with P32d3 connectors, so they work with factory HID ballasts. The Morimoto page notes reliability with finicky OEM Nissan and Infiniti ballasts.

Do I need to buy two?

For the OSRAM, yes, since the listing is a single bulb. The Morimoto comes as a pair. Replacing both sides at once keeps color and output matched.
