I use Schwab for iron condors with SPX and they get filled at the bid/ask if selling/buying, and the spread can be pretty wide. I assume the orders go to CBOE and broker doesn’t matter, but interested if anyone has expertise getting mid spread fills for SPX on IBKR or other broker?
Are SPX fills equal across brokerages

No some are bettee than other. Why i couldnt tell you though.
For SPX, execution quality will basically be the same regardless of your broker. This is because it’s a single-listed product and all orders are sent to the same execution venue.
you should be getting the mid price, or better.
Your fill quality should be relatively consistent and any change between them is essentially just random and or quality of your broker’s tech stack
