If you read you would realize that SATA includes PCIe as part of the spec. SATA Express and M.2 both have options to support legacy SATA and therefore isn't "exactly the same thing" but is a superset of both.But for PCIe M.2 SSDs, yes they are the same.
If it's like CoC it won't be bad. CoC is playable without spending money but I put in $10 since I enjoy it enough
This is for the MBA but my MBPr shows the same: ACHI 1.30.  
 Lol...grasping at straws are we?  You didn't know SATAExpress was PCIe, too arrogant to check and too silly to concede gracefully.   Did you ever consider that there are PCIe 2.0 SATA Express implementations and there are PCIe 3.0 SATA Express implementations and therefore there shall be PCIe 4.0 SATA Express implementations?  The spec covers future PCIe versions for both M.2 and SATA Express when they appear. Them straws sure are slippery.  Hard to grasp no matter how...
 SATAExpress is PCIe.  Read the link: "The SATA Express connector used on the host side is backward compatible with the standard 3.5-inch SATA data connector,[2] while it also provides multiple PCI Express lanes as a pure PCI Express connection to the storage device." PCIe is not currently up to 256 Gibit/s. The PCIe 4 spec isn't final until late 2015.   PCIe is 7.877 Gbit/s per lane in the v3 spec.  SATAExpress offers up to 4 PCIe lanes for a total of 31.5 Gibit/s.  Not...
 Lead a horse to water but you can't make him click a link. SATAExpress implements both SATA and PCIe.  Which you would know if you took 1 second to click on a link. SATAExpress PCIe SSDs (in either desktop or M.2 physical formats) do not use the legacy SATA chain but connect to one of two types of PCIe controllers (AHCI or NVMe) and has access to one to four PCI Express lanes worth of bandwidth.  Which you would know if you took 1 second to click on a link.   Therefore...
It doesn't impact latency. The legacy SATA paths are not used. Power impact is likely minimal. The trade off is you can use legacy drives if you want. Like large HDDs.Minimal googling would show it does.
You can google it yourself. In fact it's on Wikipedia.That you wouldn't take 2 seconds on your own to read that SATA Express (in both regular and the M.2 form factor for laptops) directly implements PCIe as an option makes me very disinclined to re-find and link benchmarks as "proof". Again, the PCIe Samsung SSD in the MBP and MP is available in the standard M.2 form factor. And there are faster benching PCIe SSDs in the M.2 format coming.Here's a nice diagram on Tom's...
 It's frustrating but expected from Apple.  The only way they will let the mini outperform the base iMac is by making it the same price.  Even then it's iffy.
 Except it's not faster than m.2 and SATA Express.  The M.2 SATA Express SSDs are no slower...especially given that the Samsung XP941 seen in the 2013 MBP can be purchased as a 512GB M.2 PCIe SSD. It is a shame that the MBP isn't using the M.2 standard.  It would be a little bigger but probably not much.  There's no significant advantage for the desktop market for soldered RAM and several downsides.  The stacked in-package RAM is different and separate from DRAM.
