Simultaneous execution vs leader-follower
"Simultaneous execution" is one copy method. CrossTrade runs three.
QuantLynk's homepage leads with "Simultaneous account execution, not broken 'leader-follower' like other providers," and its setup is "Create trade groups & choose your alert." Sending one alert to a group of accounts at once is a sound design, and CrossTrade does it too: multi-account webhooks send one alert to several accounts in parallel with no leader, and the Tradovate trade copier's Signal mode sends every follower its order in parallel as soon as Tradovate accepts the leader's.
What an alert-and-group design can't do on its own is copy a trade that never passed through it: a trade placed by hand in Tradovate, NinjaTrader 8 or TradingView's trading panel, a stop dragged on the chart, a working order canceled. That is what CrossTrade's Execution and Order modes are for. They watch the leader account at the broker, so they see those trades whatever placed them.
CrossTrade value Pick the copy method per copier Signal mode for alerts and code, Execution mode for every fill, and Order mode (beta on Tradovate) for every working order. NinjaTrader 8 copiers run Order or Execution mode.

On speed: QuantLynk's homepage quotes both "Less than 50 millisecond execution speeds" and "Simultaneous, less than 200ms." CrossTrade does not publish a latency figure. A copy that lands a few milliseconds later won't fail an evaluation, but a trade the copier never saw will, so measure timing on your own accounts in Demo rather than trusting anyone's homepage, ours included.
