if you mean compliance in terms of vertical travel, there's no
difference. if you mean compliance in terms of geometry control and
degrees of freedom, wishbones are the way to go. basically, you can
keep the camber appropriate to lean angle /both/ sides of the car. with
mcpherson, you can kinda-sorta get it ok-ish for the outer wheel, but
the inner one goes to heck. in low traction environs like rallying on
dirt, it doesn't matter, hence subaru dominance in that arena. but on
black top, wishbone is the way to go. somewhere on the web is a table
of cornering g's pulled by different compact sport cars from the 80's &
90's. the crx was [is] better than than any other car in it's
class/tire width. look at any mcpherson vs. wishbone - they all have
wider tires just to keep the thing on the road. better yet, check out
any wide-tired car like bmw in a parking lot with the wheels at full
lock. see how much [how little] rubber is on the road on the inside tire?

that's minor. biggest advantage is /significant/ cost saving - much
lower component count and each component that's left is /much/ cheaper
to manufacture. look at the [forged?] knuckle on an integra - that
thing is at least 3 forming operations, each needing very expensive
tooling. a strut just has a cast sub axle bolted on the bottom.

there's plenty of room. mcpherson is all about cost. end of story.
if you want a car that can be tweaked and really handle on the curves,
get a post 88, pre-2000 civic, a post 88 crx, post 89 integra or a
prelude. the 06 si has a nice motor, but that's about it. seriously,
if you sell that car, you'll have money to spare for a good base car
from the above, /and/ a motor like this:
