i use FL so i cant speak on ableton. but FL comes with some really powerful synths built in. if you can learn 3xosc, you can learn any subtractive synth. harmor and sytrus are MONSTERS, ive barely scratched the surface of them. some of the effects aren't amazing (i avoid the fruity reverbs lately), they're very good tools to learn on. so i would start there; that applies to any DAW, u can learn just as much with ableton's stock stuff.

almost every plugin has a manual to go with it (and FL has it's own online!). find it, read through it, read through it again when ur uninspired. learning what the knobs do, how they affect sounds, will honestly help you SO much more than any of the millions of How Too Scrillex Bas's tutorials. i spent way too long watching SeamlessR (who is good!) and learned wayy to little from it by comparison to messing around and making stupid sounds.

anyhoo. to be less preachy, here are the plugins i've been using lately! i make pretty, glitchy distortion-y stuff if that helps.
3xosc
sylenth1 (90% of the time)
massive sometimes
ott
valhalla reverbs
all the fruity compressor/stereo shaper/etc stuff is good
ESPECIALLY fruity waveshaper and granulizer
TAL-bitcrusher

Thanks for the comments so far, appreciate it all!

When I was starting out I only watched YouTube tutorial videos.

These two guys really helped me:

Best of luck man!

Whatever DAW you use, my advice is to LEARN TO USE THE STOCK PLUGINS. Too many people watch a tutorial that uses Sylenth or Massive and immediately assume they need it to sound good. Especially Sylenth. FL's stock plugins can do just about anything Sylenth can, but it forces you to mess around with them and (god forbid) learn what the controls do.

I can support this, I personally use Ableton because it looks very clean and seemed easiest to use. However it is all preference. My advice is to you is to look at DAW introduction tutorials online and then make you decision based on what seems easiest for you to learn. I would fool around with the stock plugins before getting into any other external plugins.

To be honest I mostly use the ableton stock plugins in my tracks because they can pretty much do what any other external plugin is capable of. Don't think you need expensive equipment or VST/plugins to make a great track.
