My first solo was in a knackered Tomahawk, which I was happy to fly on the basis that since I was in it less than 5% of the time if it fell apart it was 95% likely to do it with somebody else.
I did all of my PPL training on that basis.
And I wouldn't do any of it again, even if you paid me for it
Not sure why a twin would be particularly addictive. A half decent piston tourer (say 250HP+) is just as quick and probably quicker getting off the runway, and no worse after that. And you are doing that on about 60% of the fuel.
If I was after reliability, I'd buy a single turboprop. As one owner told me "there is only one thing better than a PT6 and that is having two of them"
