There are lots and lots and lots of threads about this; search around.

On Road: Sora, Tiagra, 105, Ultegra, Dura Ace.

Deore, LX, etc. are mountain; don't know their order.

Shimano lists their groups in descending order of quality on their website.
Road
Mountain
It's tricky because some groups are special function (Saint and Hone are specialized groups for greater strength and durability, for high-abuse situations, Saint higher than Hone).

Mountain group order: Tourney, Altus, Acera, Alivio, Deore, LX, XT, XTR.
Mtn groups start at a lower quality-level than road groups, because there's much more of a market for low-end mountain bikes; there's really no market for low-end road bikes.

Like Timcupery said, the website enlightens all...

That said there heave been many times in the past and even present where just because XTR / Dura-Ace is top of the line, that doesn't mean it's the best choice for everyone. Typically the absolute top of the line stuff has at least one or two interchangability issues with other groups. (For example, the XTR group before 2007 used a different bolt size for the chainrings on the front. If you had to replace them you were stuck with the expensive shimano stuff instead of having other options. I'm not sure if this is the case with the current model year or not.)

I fully agree. Plus, the top-of-the-line groups are sometimes less durable because they optimize lightweight (e.g., Titanium cassette, aluminum freehub body, etc.)
This is even more pronounced with Campagnolo, where Chorus is usually the same mechanisms as Record but has less carbon fiber and titanium bolts, opting for aluminum and steel bolts. Same with SRAM Rival (the slightly-lower-level group) compared to the top-line SRAM Force gruppo.
