Do you guys make your own synth sounds or use presets?

So i am pretty new to the music production game but have been getting more into it the past few months. I hope to be more active on the community s as i just joined.

Do you guys use presets or make your own? how long did it take you to start making the sound you want?

Whats your preferred synth?

I like massive and sylenth, i am better at using massive for making my own sounds but i really like the stuff sylenth can make. i figure id practice with these 2 before i step into another synth.
