Personally I prefer the self verification of the rolls over the auto verification of moneypots provably fair system.
Just to be clear, you can self-verify MP bets too. It's just a pain in the ass.
Here's the procedure for manual verification both:
Just-Dice:
1. Record the server seed hash
2. Change the client seed to something you picked
3. <make 1 or more bets> (and remember the order, direction and amount you bet)
4. Ask the server to reveal the server seed
5. Use a script to generate the outcomes
6. Compare the lists
MoneyPot:
1. Record the server seed hash
2. Change the client seed to something you picked
3. <make 1 bet>
4. Use a script to check the outcome, given the bet result (and client seed)
5. Compare

So the advantage to JD's scheme, is if you trust your memory (or bet predictably) you can bet over and over. It's honestly much better for a human. But MPs advantage is it happens on a per-bet basis, and if you trust the verification script you can automate it. All MP casinos (with the exception of DustDice) are third-party, and their interests strongly align with players (they make more money by having players win than lose)
