does someone have experience with the first 7 devices from left of this comparison

they go from 30 - 100 EUR
for just routing the teddycloud my favorite would be the shadow gl-ar300m16 for ~30 EUR. Small size is also a plus. According to openwrt.org the 16mb flash and 128mb ram are just bare minimum.
in some forums it is mentioned that qualcom cpus are better supported by “clean” open-wrt and the Gl-Axt1800 has best wifi but is not (yet?) supported by “clean” open-wrt.
My favorite for now s the gl-a1300 so I can play a bit more with extensions and will have a faster connection to my home network than with the shadow.
