people have their own preference on addons, some may like it but some dun

it's like how some people would stick to damagemeter over dr damage
it's like how some people prefer default blizz UI over other UI enhance
it's like how some people still going, 'LULULULULULULUL U R NUB, UR GEE-ESS IZ LOW' when himself dun even bother to know the fight and relied on his guildies (aka carried)

as for me, the UI has higher memory; it's a no-no for me
