I believe dave 3d and Jarrod tech has both reviewed Valeon - or promotheus its called - fast but it can get hot and crap battery as you said.
Ionico has been reviewed here - bear in mind its tongfang chasis - but intel - check the vid out in show off your laptop section but i would defo go amd...
Other difference is that Elimina is Clevo whilst Pro is Tong Fang. There seems to be different views here as to the pro and cons of each.

also Pro has a 165Hz QHD Panel as opposed to 144Hz FHD Panel.
Think...
recoil is lot thicker, has mechanical keyboard, aluminium and has bigger battery.
Not sure what chassis Recoil is.
Ionico is TongFang.
I wonder why Ionico 15inch has such small battery compared to other 15inch.
