I must be really good at it because after putting a few bars together I am too relaxed to have any motivation to write any more.


So that's why the genre typically has two chords that repeat very, very slowly for five minutes and then fade away on a wash of reverb. It's stoner music! I can relate.
What exactly is the distinction you are making here?
The distinction is that no synthesizer is capable of generating every imaginable sound. Designers have a general type of music/market in mind when they decide what features to include.
EDM likes bright, aggressive, fizzy sounds, swept highly-resonant filters, arpeggiators and randomizable step sequencers. EDM is all about exotic tonality set to a simple, repetitive beat. Because it is so repetitive and quantized, tonal interest is the only thing it's got going for it. So EDM producers are always on a quest for new and interesting sounds - it's not like they can switch to a 5/4 time signature to mix things up, or use a long acoustic guitar intro to build dynamics. Many basic musical principles are off-limits to EDM producers, lest they drift too far from the required elements of the genre.
Synth vendors who want to cater to that genre are going to try and make it very easy to get those interesting sounds. Let's face it: most EDM practitioners are preset-punchers, and most are actively trying to mimic other EDM artists. Savvy synth vendors make sure that their products achieve that with a couple mouse clicks.
I also use synthesizers for tonal color, but in a more subtle way. The sounds I employ are more likely to be reminiscent of something you could actually create in acoustical reality. It might be a deep percussive hit similar to a large oil drum hanging from a rope, and mixed under traditional tom-toms. It might be a modulated soft wailing sustained tone mixed under a violin lead line, or an ethereal pad that reminds one of distant music wafting over a windswept plain.
Percussive effects require a white noise generator, and strangely, many software synthesizers don't have one. Not needed for EDM. Evolving pads need multiple independent oscillator/filter/envelope/modulation sets. Not all EDM-oriented synths offer that, because complex evolving pads aren't part of the EDM landscape. I like to base sounds off samples so that they're grounded in reality even if subsequently strangely warped. EDM is content with sawtooth and square wave oscillators.
So yeh, some synths are better suited to EDM than others, while other synths are better suited to my kind of applications. Which is not to say that the line is carved in stone.
