LGA 2011 is more for professionals and rich people as it can support CPUs like the i7 4930k (6 cores, 12 threads, over $500). LGA 1150 is more for gaming as it supports all Haswell CPUs up to the i7 4770k (the better ones are only supported by LGA 2011).
Generally if you don't have $3000 to use on the PC, you should go for LGA 1150.
In terms of the uArch, LGA1150 is currently better as it is Haswell based while LGA2011 is sitting on Ivy Bridge-E. Haswell-E will be out soon.
OP, LGA2011 has a few benefits. It has more cores (up to 6 currently), more memory channels and capacity (quad channel RAM support with up to 196GB normally) and more PCIe lanes (normally has support for at least 2 x16 PCIe 3.0 lanes).
However it is a generation behind uArch wise and also costs at least 30-50% more depending on a lot of factors. As well, games do not benefit from the extra memory bandwidth/capacity or cores currently so as of right now it is normally best for one of two people: 1. someone who games and does rendering or some other professional workstation related work or 2. someone who has lots of extra money to spend and wants the biggest ePeen.
I personally stick with LGA1150 (or whatever the next one will be) because the benefits do not outweight the price difference for me. If you plan to mostly game and do normal stuff, get something like SR-71 described.
