I use older versions of them both. They are reliable.

The caveat about True Image is that the new version which is sold each year invariably has problems with it initially. It usually takes several program updates to make them reliable.

The idea of operating without a full backup these days is quite misguided & usually causes premature baldness from tearing it out from poor program updates, fouled up programs or viruses/spyware. It's a warm fuzzy to know you can restore your whole system in under half an hour if you must.
