The only problem I know of that was unique to the 2.5 was the porous block issue. Any car running today with 50k+ on the clock almost definitely won't have that problem.
I'd say the early 2.5 and 2.7 lumps are about as solid as these engines get. Relatively low power and unstressed.
Re the 2.5 v 2.7 performance, there's very, very little in it. The main reason to go for a 2.7 is because you may end up with a slightly fresher car. But as someone mentioned above, I'd be choosing based on condition. I'd take a pin sharp 2.5 over a slightly tired 2.7 any day. If you can find a great 2.7, then you're really winning.
I'd also say a PPI is pretty pointless on these cars, assuming you generally know what you are doing when buying cars in general. It won't tell you if the IMS is about to go or if one of the heads is going to crack three months down the road.
