Discussion: Different Versions of Biolite’s Portable Grill

So one of the neat features of Biolite’s CampStove and CookStove is that they can use Biolite’s Portable Grill. In fact, my desire to have a wood stove that can grill is one of the main reasons I’m interested in Biolite’s stoves. However, I read a reddit comment about how there are at least two versions of the Portable Grill on the market today.

Here’s a screen shot showing one version:

Now here’s a screen shot showing the other version:

What do you notice that’s different between the two? At least one difference is the actual grilling surface.

In the first picture, the grill itself has round wires or rods and is made up of multiple pieces of metal attached in some way. In the second picture, it looks like the grilling surface is one giant piece of metal that’s been stamped from a metal sheet and bent into form.

Has anyone else noticed this difference? I’d like to know and/or discuss several things. 

First, is the wire version is sturdier and easier to clean than the stamped version?

Second, are there any other differences between the two types of Portable Grills?

Third, if I bought a Portable Grill today, which version would I get? Assuming the wire version is superior to the stamped version with respect to durability and ease of cleaning, my cynical self thinks I’d get the stamped version. But my optimistic, Biolite loving self says I’d get the wire version. This is begs the question: what kind of company is Biolite? A company that tweaks its product to improve it or to make it cheaper?

Any of you readers out there have any thoughts, comments or personal experiences with one or both version of the Portable Grill?

EDIT: According to REI's website as of 10am on 2/5/2017, the Portable Grill that comes in the new Campstove 2 bundle appears to be the "round wire/rod" version. This supports the conclusion that this is the updated or revised version and is what's currently being sold by Biolite.
