Interested to know who's got LSD, and your experiences with it, especially in winter.  
 
Is it a good thing to have, or unnecessary?

It's an excellent thing to have. Without it, if one tire is on ice, all the power will go to the wheel with least resistance and you will go nowhere. With a limited slip diff, it allows you to turn normally, but if there is more slippage than it locks up, causing the power to be distributed to both wheels.

Must have in the city. On the highway it’s better not to have it. That being said if you have a choice get it.

Definitely an asset to have. Like said above it makes it so much easier to get around in the city. Can be more expensive to maintain but the trade off is definitely worth it.

I assume you mean for RWD. For that, yes. FWD they called it traction control. I never liked it as it would grab the steering wheel and go where it wanted.

We had a few trucks with AWD and one with Posi...the other trucks were just regular 2WD. The 2WD would get stuck everywhere once it snowed. You would pull up to a curb and if you gave it to much gas and the rear slipped up against the curb you were screwed.  
 
The Posi could go almost anywhere the AWD trucks could go around town or through snow in the lot. I'd almost prefer Posi to anything.  
 
We had a sprinter with Limited Slip and it was a nightmare. I got it stuck in the middle of a plowed parking lot. For whatever reason thought it was too icy and it just refused to spin enough to get me started. I never drove it again.

a rear wheeler, i was not even aware you could get anything but Limited slip or posi track. as opposed to the real old ones that predated Limited slip.  
 
and to my ignorance, is not Limited slip, Posi track, traction control etc just all about the same. they all control the power to the wheels in some fashion in an attempt to limit slip on one wheel and even out the power.  
 
prior to LS, the wheel that had the least traction was the one where the power went, and you went nowhere.

being used to driving (age and experience) I tend not to panic like some and stomp on the brake in situations. But when it kicks in I find its taking away my control of the vehicle. If your not sure , find a buddy that has this option in there car and take it for a "spin" at the local shopping mall when it's closed and has some snow or ice down usually after some storm and try it out..personally I don't like the feeling of lost control. But for those who are tending to freek out and slam on the brakes for ever single squirrel that crosses their path, them this is for you.

youtube videos showing locking differential vs limited slip. Having sold Gm products for many years, I am sold on their locking diff. Would not be without it in my truck. Limited slip works, but can still slip, hence the name.  
Karen for your Home is talking about ABS.

I would never own another truck or SUV without Anti-spin. Unlike open diffs, what ever wheel has traction is the one that spins. This is all mechanical, and housed in the rear differential. Awesome.  
I like the way it works vs posi, and it is far superior vs electronic traction control.  
Once you figure out how to turn of all the electronic baby sitters, (traction control, stabilizer, roll mitigation ect ) with anti-spin & “4WD” there aren’t too many situations you cant get yourself out of a bind.  
Anti-spin isn’t perfect (locking diffs), but it’s seamlessly used at all speeds, all conditions unlike locking diffs.  
Add a good set of winter tires, your golden.  
JMO and experience.

Limited slip on my truck I never needed 4WD.  
2WD without limited slip= USELESS

I'll take a locking diff any day in lousy winter weather. LSD sounds like a close second. Probably better for daily driving.
