This. Apex made some very user-friendly rules changes lately, but they also have some very murky language in their rules—look at the part about trading news, for example. Apex doesn't clearly define what is and isn't news and exactly what counts as trading it.
On the other hand, Apex reguarly offers steep discounts -- 70-90% off. So it's worth picking up a few accounts for $20 or whatever, even if you treat them as disposable practice accounts to test strategies.
Topstep is very expensive by comparison, and the rules are unforgiving, especially considering the price point. But Topstep has the clearest documentation of all the futures prop firms I've seen.
I would look into FTMO. It's CFDs, not futures, but the company is well-established and their swing accounts have very favorable rules compared to almost every futures prop, including better drawdowns. You also get free resets if you fail the combine but remain in profit. The big downside, in the U.S. at least, is that you have to place orders using MetaTrader.
