It’s all about the pinch flats isn’t it? Unladen rolling resistance is gonna be negligible and probably not noticeable by normal humans, on 26”/650b/700c the weight saving is what 40-50g per wheel max (depending on your tubes)
I certainly noticed zero difference between the tube and less setups on my 26” and if anything the bike felt less stable tubeless on the road. Anywho, I’m a lazy bugger and can’t be arsed to check/change the sealant regularly so went back to tubes.
Inner tube is quite heavy, especially on bigger tyres from 100-200g.
Ultimately tubeless save a small amount of weight but not the main features of tubeless.
