Bit hit and miss to be honest especially kevlar.
Across 5 bikes I run a mix of sintered (yellow) and kevlar (red). The sintered are generally consistent and comparable to oem shimano pads. The backing plates are a tiny bit larger and I have had to file down an edge to get them to fit my road calipers.
The kevlar are good so long as you bed them in properly. If you don’t bed in they glaze over real easy and squeel like a pig. Also kevlar / epoxy pads are pretty porus so if anything and I mean anything gets near them that shouldn’t (like a misplaced squirt of gt45 / bike spray) it’s game over for them. Baking / bbq / blow torch methods don’t work.
When the kevlar work, they work really well. Nice initial bite and little noise. Don’t expect amazing stopping power though, it’s good but not much better than sintered (that are cheaper and last longer!)
So in summary I suggest go for the sintered!
