Lycs are more reliable...end of story
Apart from what you have written being pure
rubbish, I'd like to see you back those words up with actual statistics compared to actual hours flown world wide.
Out of 16 Continentals and 5 Lycomings and two PT-6's in the operation I am responsible for the vast majority of the engine issues have always been the Lycomings (valve stems, oil leaks, pots-off) etc etc
and their associated engine components: turbo chargers, FCUs etc. I can back that up with 18 months data and that the company has utilised TBO extension on each Continental engine (including geared engines, normally aspirated and forced inducted) coming-up to TBO. If you are having failures in conties that often then you are not operating them as per the book, end story.
