Both are rare but Silverstones are rarer as they were also not that popular a watch on launch and were sold for only 2 years perhaps against 5 'ish for Monacos. The Steve McQueen connection counts for a massive amount on the Monaco and the fact it was one of the first automatic chronographs, so the history is in its favour by a fair margin.

Values are not that far apart, the 73633, 1133G, 1533 models in good condition are not much more expensive than similar condition Silverstones, £2.75-3.5k nowadays. A bit more perhaps but not a large gulf its only the 1133b for the reasons above and the rare PVD, Chronomatic and Trans that are further ahead again (albeit by some distance)

So i'd say yes SS are rarer but rarity is only of use for driving value if the demand is equally there, its moving in the right direction on SS but i expect Monacos to remian top of the tree, you cannot buy the pedigree they have, its history...
