I started by using Stake but have switched to Interactive Brokers. Depending on your trading habits, you may find that continually having to enter the same trades on a daily basis is annoying. In IB, my trades sit there until filled or I just modify them as I need to. The interface is a real learning curve though. 
  
 Oh, and if you're planning on trading options to be with the RH YOLO crew, find an alternative as Stake doesn't do it.

Yes 100pct. IB is definitely the way to go if you are serious about trading. Stakes platform doesn't compare at all atm 
  
 But stake is free and stake is closest to Robinhood
