IMO, it depends on the genre, even subgenre. A dungeon-delving game of D&D, I think, is better played with specific wealth, while the political intrigues of Vampire work well with abstract wealth.
I think it comes down to whether there is an assumption of "off camera" income and/or having a wide variance in "loot" being a balance issue between PCs. In the former case, having abstract income that is effectively perpetual means that it would be pointless to track each tiny gold piece. For the latter, take D&D, where a penniless 20th level fighter is at a significant disadvantage against a 10th level fighter with 1,000,000 gp. Stuff needs to be tracked, maybe not to the copper, but it does need to be tallied.
I could envision a fantasy game that used abstract wealth. It would probably be much more focused on politics than on dungeon crawling, though. Likewise, I think a post-apocalyptic "modern" game, would be better served by strong accounting.
