APC vs mmcache/eaccelerator

Does anyone have any experience with both of APC and eaccelerator (nee Turck mmcache)? It seems eaccelerator is much faster but APC is written by PHP developers more closely involved with core development. If someone has experience with both and tells me that eaccelerator is just as stable and reliable and that it really is faster then I would use it. But otherwise I would have to weigh pretty heavily the reputation capital of the developers and hopefully the greater reliability of APC. Why would it be slower anyways? The pages that claim this are quite old, does anyone have any idea if these results still hold? -- greg
