Your count is probably a bit off.. considering there have been at least 5 deaths on the voyager and 2 on the submatix.. The reports don't specify if they were in mccr or scr mode, but judging by the experience level and depths involved they were probably mCCR mode..
also the count you cite 150ish includes alot of scrs and unknowns.. a quick review shows at least 26 deaths on scrs

Hello Windwalker, just saw this thread and thought I'd put in my 2c.
As somebody who did go from OC to SCR and then to CCR, I think that if rebreathers are for you, don't bother with SCR, unless you are going the RB80 route, which requires a commitment beyond many people's recreational dive ambitions and is a whole seperate discussion.
As for the rest of it, in my experience the Drager SCRs are just as much work as setting up most CCRs, maybe more. And CMF SCR units don't give you nearly the gas efficeincy as a CCR and they still vent gas about every other breath when set up to spec. Then there's the fact that not every place has nitrox but even the most remote places on earth have access to O2. In short, if you plan to travel and enjoy fish watching and/or max bottom time, there's virtually no reason to consider the CMF SCRs over a CCR.
As for M vs E CCR, just remember that in terms of relability, simple is almost always better and that extends to all sectors of RB design. There are more and less complicated ECCRs and there are more and less complicated MCCRs, each has it's particular advantages and the more time you spend comparing the different designs, the more you will understand the different design ideas and their optimal applications. You will also come to understand that the weak point of all CCRs is the O2 sensors they rely on and how best to make sure you know they are doing what they're supposed to.
And just to be clear, the only reaason I went to SCR before CCR is that there were no CCRs being offered for sale in the US when I switched to RB. Lucky for you, there are many more options now. Continue doing your homework, it should be enjoyable as most learning is when you are properly motivated, and I practically guarantee you won't regret it if you really love diving. My CCR is the best big purchase I've made in the last 10 years, I've never experienced an once of buyers remorse, which is unusual for me. Good luck to you, -Andy
