Taily OK the TBO and HSI times vary a lot model to model and are to a degree operator dependent , but as a rule the Garret times are significantly higher than the backwards air engine.
And for the noisy quote, yes taxying they are noisy, exposed compressor, with the advantage that the RPM of the compressor whilst noisy rejects ingestion of stones and fod in the main, also more ice tolerant in flight.
Not any noisier than the competitor in flight.
The -10 engines are easy to start and keep cool in the start cycle, there is no doubt the engines have evolved over a LONG time and early models were not anywhere as efficient or user friendly as the current evolution.
