I own the CMMG Banshee 10mm MK10 and the Tactical Edge RD-10 10mm  pistol.   5 trips to the firing range and 500 rounds later, here are the observations (been using Sellier & Bennott and SigSauer 180 grain FMJ):
-The CMMG radial blowback system dramatically decreases the recoil and is very evident when compared to the RD-10.  RD-10 recoil is so prominent that after several hundred rounds, I had to wear my tactical glove to reduce numbness that was developing in my index finger
-The CMMG MK10 has fired over 500 rounds with no malfunctions and no cleaning to date.  The LRBHO  on the MK10 has not malfunctioned to date. 
-The RD-10's LRBHO started malfunctioning within the first 2 magazines.  Was never able to get the LRBHO to work reliably so I removed the mechanism. 
-Within the first 50 rounds, the RD-10 starting severing the empty casings in half, causing additional malfunctions when half of the casings were not extracted from the breach.  My gunsmith tested heavier buffers until we found one that stopped the severing of the empty casings ($75 buffer & $125 of labor).
-About 100 rounds into the RD-10, the bolt carrier assembly failed (extractor stripped).  Replaced it with a KAK Industries 40-S&W-10-MM-BCG ($145.00 later)
-RD-10 now fires reliably with the KAK bolt carrier assembly and heavier buffer.  All in for the RD-10 (purchase price/tax, shipping and replacement parts), over $2,150.00
-All in with the CMMG Banshee MK10:  $1,645.00 with taxes, local pickup at RifleGear.
-CMMG MK10 came with one 30 round mag, Glock compatible.  RD-10 came with two 15 round Glock mags.

Other observation:  RD-10 is noticeably heavier with the  balance point noticeably forward of the mag well.  RD10 leverages side charging handle while the MK10 uses classic AR style charging handle.

Advantage goes to the CMMG MK10

My experience with the rather pricey RD-10, which I bought a year before the cmmg banshee MK10 was produced.....

Now I own the CMMG Banshee 10mm MK10 and the Tactical Edge RD-10 10mm  pistol.   5 trips to the firing range and 500 rounds later, here are the observations (been using Sellier & Bennott and SigSauer 180 grain FMJ):
-The CMMG radial blowback system dramatically decreases the recoil and is very evident when compared to the RD-10.  RD-10 recoil is so prominent that after several hundred rounds, I had to wear my tactical glove to reduce numbness that was developing in my index finger

-The RD-10's LRBHO started malfunctioning within the first 2 magazines.  Was never able to get the LRBHO to work reliably so I removed the mechanism.

-CMMG MK10 came with one 30 round mag, Glock compatible.  RD-10 came with two 15 round Glock mags.

Other observation:  RD-10 is noticeably heavier with the  balance point noticeably forward of the mag well.  RD10 leverages side charging handle while the MK10 uses classic AR style charging handle.  Overall the RD10 is much heavier than the Banshee MK10.

Complete advantage goes to the CMMG MK10.  With more knowledge of available components at the time, I could have built a more reliable 10mm AR pistol for half the cost of the RD10.

On the Banshee MK10, well worth the $$$ spent
