I don't think there's statistics for SETP vs METP. It's also impossible to get reliable data in any single vs twin debate, because every time a twin shuts one down and continues to destination, it doesn't end up in any statistic. Only way to get reliable data was if every flight gets somehow logged centrally, which will never happen.

A lot of flying is always about plan B or even C
Best advice I was ever given was to never do anything where there are no alternative options otherwise it's a game of Russian roulette

Turbo props maybe very reliable and engine out unlikely but having had some very unlikely occurrences in the past a single Turboprop over long stretches of water at night is a crazy risk to take
Alone it's your risk! With unknowing passengers your taking that risk decision for them
I had a client who was flying to Denmark in a TBM
I advised him to go in the day and take a longer route around the coast
You can have all the statistics in the world
If life is cruel to you you have no realistic options should that engine stop for whatever reason
I sometimes fail to understand owners who will cough up $5 million for a single PC12
Take a huge hit in depreciation to save a bit on fuel and maintenance

The same with those who get a private jet! Pay for two engines dual systems but have one heart at the controls
