Simulation Softwares

Hi,

I have problem in selecting the right circuit simulation software for understanding and designing professional electronic circuits (Analog, Digital & RF). I did some research but could not come to any conclusion.
Neglecting the price and complexity of use. Which one of these (Orcad PSpice, NI Multisim and LTSpice)

1. has the most real world components available in its library?
   
2. offers the best simulation results?
   
3. offers wide range of different analysis?
4. being used mostly in industry?
5. is a good choice as far as future industry is concerned?

Thanks
