I have no idea on what your friend said, but I’ve been trading with IB for years and with Tradier since January. I regularly place an order on Tradier that doesn’t show up as the bid/ask, even when it should. Most of the time it shows up within 5-10 seconds and there will occasionally be a 15-30 second delay, but beyond that is rare. That doesn’t happen for me at IB, though. I’ve tested it numerous times by submitting orders simultaneously on both platforms and also trying one before the other and always get quicker fills at IB for the same order. However, in my observation, the price I eventually get is only occasionally better at IB, but then the commissions/fees are always higher at IB. For reference, my average commissions costs is 1.0% of my trade at IB, while it is 0.2% at Tradier. But I’m not sure that’s a great comparison on its own since it depends on the style of trading one does. Also, it doesn't directly compare when/if fills are better at IB vs Tradier and I don't have data on that - only personal observation which could easily be biased. I am just trading options on these platforms and as long as I avoid thinly traded options and times with unusually quick price movement on the underlying, I doubt there’s enough of a difference to overcome the savings on commissions. so bottom line for me is that Tradier annoys me more, but I still use them.
