DNX/Jericho would have sufficient buffers to handle the rate conversions?

LINX went Edgecore, which was on my list given my experience with other Accton brands. Fiberstore has a switch where they actually publish the pricing vs. a bunch of mystery. 

Tomahawk and tomahawk 2 have precious little in the form of packet packet buffer (e.g. As little as 4 x 4MB for original tomahawk) which might be a problem in a environment where you need to rate convert 100G attached peers to a big bundle of 10s). 

White box Broadcom dnx / jericho is somewhat less common but does exist. 

That 40s are less popular I think is no surprise. They were / are largely consigned to datacenter applications.
