It's not so much a matter of brand as it is grind. Wedges, quarter hollows, half hollows, and 3/4 hollows are all very stiff and heavy for their size. Some full hollows are still quite stiff, but here it's just a matter of experience as to how stiff they are. Any blade described as "extra hollow ground" is probably not particularly stiff, and the same applies for any blade described as "singing" (the singing in question is sound from the blade flexing and ringing).
