With IRS it is quite a bit easier to control wheel hop. So in other words power generated is going to make you move forward, not hoping the wheel. Also unspung weight is lower with IRS than a live axle. Unsprung weight is a large demon in handling. The back end will have less of a tendency to kick out, specially when exiting a corner under throttle.

Thanks. What about what I asked about a more "luxurious" ride? Will it feel much smoother or is that a shock absorber / spring type of issue?

Well, yes. Primarily what affects one rear wheel will not cause the other wheel to move. Radical bumps can still be transmitted to the other side but you won't care. You will be busy planning to go get your wheels re-aligned.

But there is still spring and shock involved. You still need to spring the weight, and a shock to dampen the movement of said weight. It's just that IRS will use a coil-over-shock set up. A solid axle could use this, but you will also see them use leaf springs also.
