Is undergrading considered more accurate? The grading services may have slightly different standards so I look for consistency in grading.

I notice the difference primarily in the higher mint state grades where, I agree, NGC seems to be 'looser' with 70s than PCGS.
Accuracy has to be measured against some standard. I am not certain that PCGS and NGC use precisely the same grading standard, so (theoretically) they both could be completely accurate.
'World coins' also covers a very broad landscape. From ancients to modern bullion. Also, compared to US collectors, non-US collectors are not nearly as bought into the notion of TPG grading, encapsulation and authentication. I predict this will slowly change. If you talk to a classic world coin collector about the difference between a 40 and a 45, or a 61 and a 62, they will probably just smile at you (if they are kind). If they are not so kind, they may laugh in your face. And who can blame them? World coins have been collected for as long as there have been coins, approximately 2,600 years. TPGs as such have been around for about 1% of that.
I do like what NGC has done in the grading of ancient coins, and I wish they would use the same process with more modern coins. And that PCGS would join in.
In the end, you have to buy the coin and not the holder. Unless you collect holders, which I know some do.
I am a strong fan of the major TPGs, and I have as much of my collection 'slabbed' by them as possible. I do this for three reasons (in order of decreasing priority):
1) The holders provide excellent protection for the coins 2) I like having another OPINION about authenticity 3) I like having another OPINION about grade
Good thread, I look forward to reading the other answers.
