I tried the Breathos with and without insoles, but I usually prefer not to use them, and I don't use them in the Trailrocs.
I'd say the 235s are a little thicker, but it's more of a dense (but flexible) foam material than the very hard dense rubber type material used on the Breathos.
Ground feel might be better on the Breathos without insoles, but both being heavily lugged negates the ground feel pretty significantly, however, the hardness of the sole material and the shape and stiffness of the lugs on the Breathos, to me, negated any useful perception of ground feel other than pain. On short (2-3 mile) hikes they seemed fine for the most part, but I never felt "comfortable" in them. I kept waiting for them to break in, when I finally did a longer hike (20ish miles) it was hellish.
The Trailrocs to me, were instantly comfortable. Keep in mind, I'm not a minimal shoe novice either. I grew up in Central America, was barefoot most of my child hood, wore flat soled skate type shoes through the rest of my younger years, and never had any problems until I got tricked into "performance" footwear. I needed no adjustment period to switch to VFFs, and found the original KSOs to be the most comfortable, so it's not like I'm not used to extremely minimal.
Currently I'm wearing Sodhopper Stealth Trackers as my day to day shoe, including in the shop, and wore Soft Star mocs primarily, before that. Used the original Altra Instincts last winter for the insulation, but destroyed them, and they were far from ideal. Hated the high stack height and *zero* ground feel.
If the Breathos work for you, I don't want to talk you out of them. Damien Tougas seemed to really like them, and I usually take his word for it. They just didn't work for me. I think it's probably related to the fact that my feet aren't adjusting from years of problematic footwear, and I'm used to what I'm used to.
I will add however, that I tried 4 different pairs in two different sizes, and every one had major fit differences. I think the QC over at TerraPlana isn't that high.
Like I said though, the original Aquas were some of my all time favorite shoes.
