i think the primary difference is that you cannot protect your hands on the flop as well. the flop bet in structured limit is two-tiered, that is the first two rounds are 1/2 the size of the second two rounds. for this reason an expert limit player must make more creative plays to protect his hand on the flop to maintian/maximize his winrate over his playing time. also, the swings in Limit are much more difficult to overcome in the short-term which can prove to frustrate even the most experienced poker player if patience and not just understanding, but accepting the variance of the game and the amount that short term luck plays in the situation.
