I agree with Paul, whichever is the cheapest.
All have good and bad staff, all get the odd bad car, we have used Dollar most (get Express card and bypass the line) they are my 1st choice, maybe its because I have done over 20 rentals with them and have express card but I get a free upgrade almost every time. Used Alamo & Hertz last year no problem, Budget 3 or 4 times OK.
If you post your dates and best price you can find the if anyone sees cheaper they will let you know.
