qe stadium vs hk coliseum

on x'mas eve there was a concert in qe stadium which the performers had sung in hk coliseum too. it's a good chance to compare both

convenient: qe is a bit better. at least located closed to hot spots
traffic: coliseum locates just next to train station
other design: qe has a lobby to allow them to sell stuff!
theatre: qe is smaller but has better sound system & less restrictions to performers to contact audiences
