I'm tossing up between whether I would like Accuair bags or MCA Gold Series coilovers for my 2008 135i

What are the pros and cons of both (or even just bags vs coilovers) performance wise? I know it's a little like comparing apples to oranges

Realistically I have narrowed down to these 2 options because, as far as my suspension goes, I either want to go all out and do it properly or not at all

At ~$AUD2500 a corner though, MCA is significantly pricier than nearly all other suspension options (I'm going to be saving up for quite a while, or winning lotto haha), is it worth it? Has anyone had any experience with these coilovers?
