One of the most accurate rifles ever made - definitely a more accurate rifle than the 202. A masterpiece of engineering, but that results in a somewhat heavy rifle. Rear-locking with three retracting lugs, it is actually really a straight pull bolt where the initial lift actually retracts the lugs rather than turning the bolt. Probably about the smoothest action ever made, with some of the prettiest stocks and bluing ever on a factory rifle. The magnum-chambered rifles had issues with bolt compression - or probably more correctly lug compression in this design. They only stopped making them in 2008 or so from memory.
A very different rifle from the 202. Barrels don't swap. The 202 is about half a pound lighter, and is a front-locking action. If a 90 ever came up in the right price in a short action rifle, i'd probably grab one. The long action rifles are probably a touch too heavy for me.
