You need to specify your budget and intended use. There are loads of Spice simulators available. If you find LTspice difficult to use you will struggle with the rest - LTspice is one of the simplest ones to learn. Also, you need to get used to adding models to all simulators so the fact that LTspice only comes with LT models is not important.

As I said before, you need to specify your budget. If you want "Pspice" then that is the version of Spice sold by Orcad (now part of Cadence). If you want "Spice" then there are dozens of options ranging from free ones to $100,000+

For that sort of money Pspice would be a reasonable choice. Also, SIMetrix would be worth looking at. There are others but they are two that I have used. It partly depends on what you want to design with it - for example, do you want to do analogue or mixed signal IC design or only the design of discrete circuitry?
Also, the most expensive packages are not necessarily the "best". Have a look at Anasoft Superspice and Beige Bag http://www.beigebag.com/ for example. Where possible get a usable demo version before you spend your money.
