Under normal driving it should make no difference.
What I found on the LSD cars I've had is that say in the wet waiting to pull out of a busy junction or pull onto a roundabout, if you give too much power with a standard diff, the inside wheel lifts, spins and you go nowhere. If you do it with an LSD, both wheels spin and you will fish tail down the road or spin. Luckily I was quick enough to stop it happening when it did. It really doesn't come down to driving like a knobhead or anything. Pulling out of busy slippery junctions always has the potential of wheel spinning. The end result is totally different depending if an LSD is fitted or not. Neither result is particularly good if it goes wrong.
In snow, an LSD can make the difference between getting going and not, without it a single wheel will spin and you can be stuck where as with the LSD and both wheels still turning, you may get out of it.
It is swings and roundabouts really, if you over cook it it can help, and other times not, depending on the situation. In dry conditions, the LSD can be more fun. JMO.
