Best circuits simulators

Any thoughts on online circuits simulators ?

I have tried :

1. EasyEDA https://easyeda.com/

2. Every circuits http://everycircuit.com/

3. circuits-cloud http://circuits-cloud.com/

4. circuitslab https://www.circuitlab.com/

 Whats your favorite?

Perhaps more to the point, what was your favorite.
You tried four, did any or all of them do what you wanted, if not, why not.
There are so many simulators available, that it is almost impossible to recommend one over another. I would guess you found that if you did a web search. The point is, find one that looks like it will do what you need, and learn it thoroughly. They all have their quirks and idiosyncrasies, so it can take a while. When you get into using them more seriously, then model availability becomes important, standard Spice models should run without needing major modifications on the simulator of choice.
If you don't have a fast, reliable internet connection, I would avoid the cloud based simulators.

Hi Layla,

Im using http://partsim.com a full SPICE simulation engine, web-based schematic capture tool, and a graphical waveform viewer. It has examples http://www.partsim.com/examples/
which you could check out. The good thing about the tool is that you can create your own SPICE Model which you can include in your circuit. It's an easy and user-friendly tool. It has 4 simulations ranging from DC Bias, DC Analysis, AC Analysis and Transient Analysis. Hope it helps.

Warm Regards,
Emman

It depends on purposes of using circuit simulators
