Well if you need a reason to justify buying a new light, you may not be quite as far gone as some of the rest of us So I'm not sure if my comments will help or not.
Personally, I think the SC600mk3 HI is better than the MH20 in every way (well, the MH20 has a better built-in charger...). So for me that's good enough. The Zebra is brighter, more intense, has a much cleaner tint, better regulation, better UI, and its much smaller. Here's a comparison photo for you:
Te be fair though, I never loved the MH20. When I need a "throwy" edc-able light with built-in charging I reach for that Manker. When I don't need the built-in charging I'll definitely be reaching for the new Zebra. The MH20 is just taking up room on the shelf.
Being this is my first post and new to here, could you list what those lights are. Thank You
