I chose to live in because one of my accounts is based here although I could have run it out of Vegas.
I have 1 son in Vegas and 1 in Phoenix.
In random order
1- better medical care; we use the Mayo Clinic
2- airports are the same
3- traffic is better & road improvements are done faster (see the 15 in Vegas)
4- being from NY taxes are much better
5- gas is cheaper
6- warmer in the winter; 74 today
7- more pro and college sports
8-better entertainment
9-Slightly cheaper
