Well, both the M11R and the V11R are released now:

RRT-01:

The M11R has a magnetic ring with 50 microamp standby, and only 3 levels of brightness.
The V11R has infinite control of brightness, but has no micro-amperage standby built into the ring; rather it uses a tail end clicky, such that the user must constantly flip the V11R 180 degrees to operate the tail end switch, and the neck located magnetic ring - else use two hands.
Thus, personally for me, the RRT-01 gets my vote here, for a magnetic ring with both micro-amperage standby, and continuously infinite brightness control.
The Sunways are famous for short ring travel.
The Jetbeams have been famous for long ring travel in the past.
The amount of ring travel in the RRT-01 has not yet been documented???
Furthermore, it seems from photographs that the RRT-01 has a deliberate/intentional shallow reflector depth, for only 113 meters of throw [versus the Sunways' deeper reflector for 130 meters of throw], however I wouldn't be surprised to find that the RRT-01 will have a wider lateral illumination/spill of light for greater practicality.
What's more, the extra floodiness of the RRT-01's beam matches it's neck mounted magnetic ring UI with micro-amperage standby which requires the handshake grip for operation on/off.
However, I do like the softer and more gentlemanly styling of the Sunways more than the rugged looking Jetbeam.
I particularly like the transverse heat sink styling on the Sunways, over the longitudinal thumb/finger wells on the Jetbeam' head, supposedly so we can grip the head to rotate it, but we know that the head is in fact immobile.
The RRT-01 does have a nicer SS bezel, and a nicer Ti clip; the M11R's Ti clip is nice, but it's right angle bend doesn't look as graceful as the RRT-01's longitudinal McGizmo-like clip.
The white labeling from standby, to minimum to maximum brightness levels on the Sunways are better too, than the RRT-01's zero labeling.
Hand Shake Grip, Magnetic Ring Standby with Pure Flood Beam
Overall, for me and my tastes, the RRT-01 with: the micro-amperage standby in the magnetic ring for the handshake grip, the continuously infinite brightness adjustment, not to mention the lower low of 0.005 lumen, the matching floodier nature of the beam albeit with less throw, and there's the more secure screwed-on titanium clip too, is the best package of the three.
I can live with the RRT-01's slightly lesser styling, the absence of labeling on the magnetic ring, and a fraction less efficiency from the XM-L T6 bin emitter.
Overhand Grip, Tail End Switch with Flood-Throw Beam
For those who'd like more throw [flood-throw combinations], the extra throw of the V11R combines and packages nicely with it's tail end switch for the overhand grip, since throw beams encourage the higher overhand grip, to maximise the throw.
However, what happened to the M11R's micro-amperage standby on the magnetic ring?
And what happened to the M11R's nice securely fastened screwed-on titanium clip?
A surprising lapse in packaging for the new Sunwayman V11R?
