I wouldn't be as much concerned about brands as I would be about the Dealer or Rental House. What are rental cost, What is guaranteed availability, How long can you be broken down before you have a replacement on site, contracts will vary. You can do some research on fuel consumption, cycle times Etc. but the dealer is the key to a succesfull rental. I haven't been in it for a few years, but Terex had a bad rap for a while on poor dealer support.
The other thing is site evaluation, do you need a 25 ton or a 40 ton truck, Ground conditions are important, soft ground with no base or manuverability on a smaller site might be better with a lighter truck, hard ground, longer haul might mean a larger truck.
Anyway the dealer is your main concern, check references, a good dealer will give you several.
