They say older players are easier to understand than modern players, which is true to an extent. A 1000 player isn't going to understand all the computerized theory that Kasparov, Kramnik, Carlsen, etc had.
That said, the Romantic era is TOO OLD. Even beginners that put any effort into learning can figure out that what was done in the 1800 isn't really viable any more.
I think the ideal player to study if you are going to narrow yourself down to 1 player is probably Capablanca. His attitude was to keep the position simple.
However, no matter who you study, there is a major difference between unannotated Capablanca games, Computer-Annotated Capablanca Games, Densely Annotated Capablanca Games, and Annotations proper for a beginner of Capablanca Games.
I think a player should study a basic endgame book, a basic tactics book, a basic book on strategy, and then Capablanca Move by Move!

Many other interesting questions from odds games to the length of world champion matches, but the ones above I felt were more on topic to this thread.
