I worked at Planet Hollywood's Book for a while
Honestly it depends on what you are looking for
LVH has the most options and is the largest book. It's also one of the busiest, so you have to get there at 8am(games start at 9am there) or you won't have a seat
I like the setup at the Palms and Hard Rock the best(they have the same book setup). Not that many chairs though, but they are large and comfy, so you have to get there early. Venetian also has a similar setup but its too busy on gamedays
Luxor is good if you just want to watch one game, as its not that busy yet has a great setup, but if you are trying to watch multiple games at once go elsewhere since it only has a few big screens
Mandalay Bay is a good bet, its big, but the problem is that the seating is a bunch of school style desks, so its not the most comfortable.
MGM Grand is weird, its kind of a horseshoe shape, but you can get some sofa style chairs. Get there early if you want a seat though
Bally's is big, but its hard to find. It's like a maze getting there. But it does its job
Treasure Island is small but I loved going there during the week to watch baseball and WNBA since it felt the most intimate. Flamingo has a similar style book, but smaller.
Pretty much any sportsbook for Saturday/Sunday you have to get there no later than one hour before the first games kick or you are going to be standing
As far as books to avoid:
Bellagio - You aren't getting a seat here unless you pay for it, because the hosts will put butts in the seats for those who do. I hate this book.
Caesers Palace - Pretty much the same as Bellagio. You have to pay off the casino host for the right to sit in this book. What do you expect from a casino that caters to $30,000 a year millionaires? I hate this book too. Far better options
Rio - It's kind of like Treasure Island but more open and kind of small. Screens are small too
Palazzo - Its a restraunt, don't do it
Wynn - I hate this place, caters too much to horse racing, and rude staff. Also its all desk style seating, no sofa style chairs, and they are usually all taken or reserved. Going to have to pay to sit here on gamedays.
New York New York - Too small
The M - Not only is it far away, but the chairs are extremely uncomfortable, might as well stand
Anywhere downtown - Too small
When it comes to betting lines, you can get your best values at the LVH or Palms/Hard Rock/Venetian. MGM and Caesers properties lines are too juiced because of the sheer amount of public bets they get.
