Absolutely I'd take the Main Event entry. As others pointed out there's more chance to win because the top 1000 places get paid and while winning the final table is preferred, just cashing in that event is a serious achievement.
Secound,becouse you in tabe with 9 players and you have better chances to win and give all prize,definitely a sekund choice easily to win 9 players of 10k to WSOP i think that,real think that
15% Cash WSOP but if 90% of the field are better than you, small chance of cashing.
1 in 10 chance to win $100K against variable abilities, alot better chance to bink
