The Trump tournament structures are pretty bad. $85+15 gets you T400 with an optional rebuy for $40 which gets you another T400. So, T800 to start. You can rebuy when you're below T400 for $40 or do a double rebuy when you are broke. There's an add-on at the end of the first hour for $60 gets you, as I recall T800. Levels are 15 minutes. After the rebuy period, it's a crap shoot mostly. However, the players are terrible, so you can get lucky. Usually around 140-150 players with the final table being paid. I don't recall the prize pools - my only cash was in a special tournament there that had a much larger prize pool than normal.
I believe the Resorts weekly tournament is on Thursdays and is like $330 or so. Call for details.
Where you play depends on the limits you want and how claustrophobic you are. Also, whether you are immuno-suppressed in any way.
If you want lower than 5/10, then Trump is your choice. If you want abundant higher limit action, Resorts is your choice. If you don't like small spaces, don't play at Resorts (I'm not kidding here). If you have any germ issues, the Trump chips are filthy; I know all poker chips are filthy, but Trump's take the cake, so to speak.
