Siimulators for Analog IC Design

I am starting to learn Analog IC Design. Could anyone help me? There are two simulators that I don't know to choose.
1) LTspice
2) Cadence
Could you tell me which one is better and maybe their advantages and disavantages of them?

There are many, many others as well. And there are many
archived discussions about their pros and cons.

LTSpice has nothing to do with IC design, it is a nice
enough tool, especially since it's free and integrated
with a schematic capture and a waveform viewer. But
you will find no PDKs for any foundry flow, supporting
it.

Cadence, that's what you use if you're spending
somebody else's money. It's one of the supported-
everywhere tool sets, for foundry tapeouts. Everybody
hates them, just like Microsoft, and for similar reasons
(but Microsoft looks like a cuddly little bunny when it
comes to pricing and license terms).

Thanks, if so I think I will go for cadence.
I have searched the forum about pros and cons of cadence but it seems rare.
