resistors are in zigzag shape
...
components are missing right out the box (triacs, for example) and you have to search, download and install separately.

Also, it does not considers limit of the components

Another "niggle" is its habit of showing ac sources using a classic DC generator symbol.

LT Spice assumed that the two LC networks were perfectly identical
- squared shaped symbol for resistor is in [Misc] directory, named 'EuropeanResistor'
- triac symbol is in [Misc] directory, named 'TRIAC', comes with the default install
- components limits are included in the model, not in LTspice itself. So if we chose, say a model of transistor that simulates the reversed breakdown voltages, LTspice will consider those limits, too. This is an example of a 2N3904 with breakdown:
The upper plot is without breakdown voltages included. The second plot is for the same type of transistor, just that the model now includes breakdown voltages. The model 2N3904 is included in LTspice by default, but BD3904_BD is not. Second one is from Bordodynov's library.
First thing after installing LTspice would be to add the Bordodynov's library, see
https://ltwiki.org/?title=Components_Library_and_Circuits. That library includes many additional models, components and symbols. Apart from models and symbols, Bordodynov's library has many interesting circuits and examples, too.
Anyway, the main idea with simulators, in general, is to see how a schematic works, not how it breaks. Most models won't include breakdown condition, unless the breakdown is essential for normal functioning (like in a Zener diode).
- the other symbol for AC sources is just like the other "missing" symbols, in the [Misc] category, named 'signal'
- in LTspice, the values are exact, so 2 LC with the same values for L and C will be identical. Same, 2 transistors of the same model will be perfectly identical. When needed, deviations can be specified manually different ways.
Not trying to convince anybody to use something they don't like. Writing all these when I see such posts (deterring from using LTspice or other simulators), because no longer than a few decades ago I've read an article from Bob Pease, where he was ranting against simulators. That rant article, plus the quote "
My favorite programming language is soldering", made me to avoid/disregard simulators and programming.
Both of those ideas turned out to be a damaging advice for me. I was a kiddo back then, and took that rant as a must-follow life-guideline. Took me years to realize it's the contrary: both simulation and programming are not something to stay away from. The hardest prison to escape is the cage of our own mind.
As anything else, simulation has its limitations, traps and disadvantages. But overall, simulation can be very helpful. Of course, the ultimate test is to put the ideas in practice and build the physical circuit, nothing can beat the joy of doing that.
