I depends what your criteria is. Also, why do you think he moved to LHW? Liles turned down 7 figures, at which point Jack O'Halloran walked away from him. The Benn fight was hard to make. He went up to HW and only missed Roch, a faded Nunn and DM, and everyone knows neither guy would travel.
Eubank didn't want to know at SMW, and was lucky to beat Schommer, Close and Benn. Benn was pretty much done after G man.
He fought the best at SMW in Toney. He fought nearly all of his contemporaries at LHW. Go and look where they were ranked.
Mid 30's I mean winning titles from middle to HW and then coming back down to recapturing the LHW crown def gives him the rankings
