I will show you guys trading for a funded account is a worse option as compared with trading with your challenge fee.
Assume traders A and B have the same trading skill level.
A pays $429 to earn a funded account.
B trades on $429 at a small forex broker account, which allows him to trade smaller unit.
Here is such a broker.It offers 500 times leverage and low trading cost that is roughly comparable to trading futures.

And also if you want to trade ES,NQ and YM, it offers US indices products.
Since A need to make 10% and can not exceed 10% drawdown, or he will lose $429.
B can increase his leverage 10 times as A and if he lose 100% he lose $429.
So both have the same risk.
Assume A manages to make 10% and earn a funded account at the end of two months.
Assume there are 42 trading days in two months. So A make average daily profit of 0.0023(1.0023^42=10%).
While B uses 10 times leverage and make average daily profit of 0.023.
So B make 266% profit at the end of two months.( 1.023 ^42=266%)
At the end of two months: A earns a funded account; B makes $429X266%=$1141.
At the end of 4 months: A make $2000(25000X10%X80%); B makes $1141X266%=$3035
At the end of 6 months: A makes $2000; B makes 3035X266%=$8073.
At the end of 8 months: A makes $2000; B makes 8073X266%=$21474.
