On the whole the Altium footprints are pretty good. But as Xiofan 
said, process differences in production environments can become 
significant. One thing that influences footprints where I work is the 
use of in-circuit testing and flying probe testing. We will often 
have to extend the pads of things like TQFP or PQFP packages so that 
the probe can land. Another factor is the differing sizes of 
components. We often have to put rather large things like D3 power 
devices on the same board as BGA's and 0402 passives, so we need to 
ensure we get enough solder on the big packages whilst not flooding 
the little guys.

What Altium version are you using? I have been a Protel/Altium user 
for probably 20 years - since the DOS days - I am currently at 6.8 
something. At the $job we are a Mentor Graphics/PADS-PCB house (and I 
don't do any PCB design), I have a small 'side' business which is 
where I use Altium.
