You heard wrong. The xbox  is not better. Here is a comparison;
The 360's Xenos is more advanced than the PS3's RSX. Rather than having separate pixel and vertex shaders the Xenos has a unified pipeline, so each of the 48 shaders can do either pixel or vertex operations. This means that generally the Xenos can be pushed to the max, with all 48 shaders busy, rather than on the PS3 where some of its fixed shaders are likely to be unused.
The PS3 was designed for the SPE's to supplement graphical processing though, so the PS3 is capable of producing better graphics than the Xbox 360.
Blu-ray beats DVD9 hands down, in every respect it is faster* and much larger. Larger means bigger games, and better graphics (most games graphic is pre-render and just assembled by the console (with some effects added), more space means better graphics). The PS3's all come with a hard drive, so games can cache data for faster reading.
* Technically there are parts of DVD9 that read faster than the blu-ray (blu-ray reads the same speed throughout the whole disk, DVD9 is faster on the outer edge)
The 360 has 3 PPC cores, with SIMD (single instruction multiple data) extensions (each Core can process as either a CPU or a Vector processor). The Cell has one PPC core and six available SIMD processors. Vector processors are very good at doing computations, or the same operation on multiple bits of data at the same time. This is the ideal kind of processor for graphics, physics or sound (in fact the GPU is a prime example of a specialized SIMD processor) which is exactly the kind of thing a games console spends most of its time doing.
The problem is that SIMD processors require the programmer optimize their code in a certain way. This requires different thinking and experience.
The 360 has a much larger catalog than the PS3, and some pretty good exclusives. Early dual releases look or ran much better on the 360 as developers produced lazy PS3 ports. Recent releases like Assassins Creed, Devil may cry 4 and Call of Duty 4 look and play the same on both Consoles.
There is a growing catalog of exclusive releases for the PS3, taking advantage of the cell and blu-ray to produce games that are simply not possible on the 360.
Both Consoles have the same amount of memory, though it is configured differently, there are pluses and minuses to both configurations. You will often see a figure quoted on bandwidth with the 360 having 256GB/S, it does for all of 10MB. The effective bandwidth is similar on both Consoles.
For most people whose online experience consists of matchmaking for multiplayer the services are essentially the same. Xbox live has more additional functionality than PS3, but then it costs $50/year rather than being free.
The PS3 failure rate is quoted at between 0.5-2%, the 360 has failure rates of between 16-33%.
The PS3 has built in wireless and you can watch blu-ray movies and DVD's without requiring additional purchases.
The 360 is cheaper, but in the case of 360 vs PS3, you get what you pay for.
