Hakuhodo J5543 ($60) is very similar and is only 2mm shorter in length and thickness (though Hakuhodo lists it as 11.5mm in thickness, mine is 18mm after washing and use)–it is not quite as dense, which results in a lighter application, though I felt realistically you can layer and apply as much/as little with either brush, it’s a matter of technique, pressure, and amount of product you initially pick-up. I also think that many will prefer a softer blush application to start than one that provides for a more pigmented application right off the bat. Generally, denser/thicker brushes will yield more color payoff and coverage, and then fluffier, sparser brushes will give you a softer, sheerer color payoff and coverage. I don’t have it to compare, but the J501 ($96) is longer (44mm) and less thick (16.8mm); J505 ($69) is also longer (38mm) and less thick (15mm). MAC 116 ($35) is much less dense, not as soft, and is narrower/more flared.
