Robinhood is great if you're investing like $5k or $10k, not fuckin $100k on a shitty app like an autistic fucktard

I disagree. I haven't had huge problems. Just a couple outages lasting a few hours here and there.  
  
 But if you trade options daily, I would suggest Interactive Brokers. I mostly stick with equities so I haven't had the big problems like not being able to sell options before expiration.
