They're two different lights. The Dereelight CL1H 2.0 is more of an all-around light, while the LP MRV is all about throw. What do you want?
The CL1H is smaller and more compact (smaller diameter head), so it's much easier to carry and/or EDC. The bezel down clip makes it hide away in your pocket easily, while leaving enough exposed area (the tailcap) for fast drawing when you need it. The head is small enough that it doesn't make a huge bulge in your pocket. Throw is quite good with the smooth reflector, tho personally I prefer the OP reflector for a smoother beam. Spill is very useable. Has low and high levels and low runs for a very long time on an 18650 with perfect regulation.
The MRV is all about throw. If that's what you want and don't mind sacrificing size and pocketability (will need to either backpack it, holster it, or jacket pocket it), then the MRV is your throw monster. Regulation is not as good on high as it's trying to make max output and max throw, but the eye will see little difference during use even tho output isn't flat. Along with being a larger diameter, it's longer also, so again, less compact. The Tiablo is also one to consider if you're interested in the MRV, tho at the price you mentioned, I assume you're getting from DX in which case the Tiablo is much pricier.
For me, I prefer the CL1H as it's more of an all-around light I can use in various situations, including indoors. For throw, I have my SL TL-3.
