You're kidding, right? The Siemens (now Epcos) stacked poly caps are known for their very low inductance, and are specifically used in ps bypass of high speed circuity. As to an objective/subjective preference for polypropolene over polyester, that may be.... but Epcos also makes these stacked architechture caps in polypropolene, though more limited values, the .01 being among them. The nekk'd stacked polyester from Epcos, available from Maplin in the UK, are legendary for that application. Go to digikey, and download the PDFs, and then tell us as to their applicability. The encapsulated Epcos polyesters are series B3252xxx and the polypropolenes ar B3262xxx.
