Heres my opinion, weighted lee dodged dosu's attack but apparently its a sound attack which lee did'nt see and has no intel on, so he fell pray to it, sasuke might fall for that too because the attack can't be seen
While CM1 sasuke dodged a supersonic blast from zoku while carrying naruto and sasuke, that does'nt mean lee can't do the same because the attacks are two different types of attacks, one is a supersonic blasts while the other is a sound attack which catches the opponent offguard, I believe lee without weights is faster than cm1 sasuke pre lee training
While I believe sasuke with 3 tomoe after lee training beats lee because ofcourse he has lee speed, versatility with chidor, katon and weapons, precog, lee can't land a hit, and sasuke just basically predicts and times his attack like he did against KN0 naruto, CM1 sasuke will be boasted even more, his chances would be higher, with cm2 he would curbstomp lee without gates, though I think drunken lee would be on par with sasuke with 2 sharingan and no curse mode due to his unorthorodox fighting style
