A lot of this depends on WHICH Trooper you're looking at.
The original Colt Trooper as made from 1953 to 1969 is basically the same gun as the Colt Python.
The only real difference is, the Python is essentially a Trooper with a heavy lugged barrel, a much finer blue job, and a more refined and tuned action.
For this reason, the Trooper is often called a "poor man's Python".
The other Trooper is actually the Trooper Mark III and Mark V.
Many people neglect to add the "Mark III or V" identification to the Trooper name, and this leads to confusion.
These models were made from 1969 into the mid-1980's and were later used as the basis of the King Cobra.
These are totally different guns, and have nothing in common with the original Trooper or the Python.
These are extremely strong, tough guns, and are amazingly high quality compared to todays revolvers.
In either case, these Colt's are very high quality revolvers.
