I can't recommend any prop from here, but to get an educated response from those that can, you will need to provide more information about what you are looking for. Size of your deposit? Manual or automated trading? Country where you live? Asset class? Etc.....
I looked into trading for them but they do not have SPX options available to trade. When I calculated trading SPY (After trading 10X more contracts) my commissions and fees were to high. When you add in all the commissions and fees I calculated that I would need to make 11-13% before I could break even. Your trading style or system may show different results.
