One witness to the Scottish Child Abuse inquiry said he had been "extremely well treated" at Smyllum Park in Lanark.
The man, now in his late 60s, said the nuns who ran the home were being unfairly portrayed as "monsters and out-and-out child beaters".
A second witness, also in his 60s, said previous evidence given to the inquiry was a "gross distortion of the truth".
Other witnesses have recounted a catalogue of abuse at Smyllum Park, which was run by the Daughters of Charity of St Vincent de Paul and closed in the 1980s.
This included beatings, humiliations, cold showers and children being force-fed inedible food.
Friday's first witness, who cannot be named, arrived at Smyllum in 1957 aged about seven.
He described his time there as "positive", and dismissed accounts of physical abuse as "absolute rubbish".
While corporal punishment was used, he said this amounted to a "tug of the ear", or the use of the belt.
"If it came to someone really misbehaving, and I mean really misbehaving, by language or fighting, then she (one of the nuns) would have had to deal out one or two of the strap," he said.
Asked about violence inflicted by the nuns, he added: "I didn't see anything like that. There are lots of lies being told.
"During my time, my window in Smyllum, I never saw any of what is being said about the nuns."
"The kicking and the slapping never happened," he said.
The witness described how he had been "shocked and horrified" to read statements from others who were children in the home.
"A lot of people I would say jumped on a bandwagon," he said.
"I think it is compensation. I really do think that is what it is about.
"There might be one or two real stories in it, but the majority in my view are untrue. Out-and-out lies."
The second witness, who also arrived at Smyllum in 1957, said corporal punishment was "used only sparingly and when children misbehaved", adding that the nuns "dedicated themselves to the well-being of all the children in their care and chastised them fairly".
He told the inquiry: "Truth has been crucified along with the Daughters of Charity and staff who worked at Smyllum Park."
He added: "Most of what has been said is not true."
