I have not traded options in TS so I don't know if it's any good, however I know that TOS is great for options as options are the product it's focused on and optimized for years so that platform may be a better choice if you don't mind having multiple accounts. That said TOS is best if you want to explore other option strategies such as straddles, ladders, iron condors bull/bear put spreads etc which some of these one could probably utilize with the SPY system trades to protect profits or reduce risks on certain trades.  I don't get into all that but I think it's something that's untapped with the SPY system and something you option experts could focus on.  

Otherwise if you only wanted to do the option trades I send out and nothing more exotic, then any broker should be fine.
