Spyke.
I own both Dainese and A-Stars and, given that most anything from Italian leather companies is quality stuff*, what becomes most important is fit. Whilst the former two are more or less made for taller folk, Spyke fits far better for those of smaller stature (I'm 5'6").
Like all things, try before you buy.
