You will get many different answers and will have to sort through a variety of opinions.
My personal view is that if you are checking bags, ride DME and use the luggage transfer service, you will arrive at your resort in about the same amount of time as you would if you collected your own bags and used another form of transport.
If you are using carry-on bags only, you certainly can get to your resort faster by using a taxi or town car service.
If you are going to collect your bags regardless, then you will get to the resort faster by using a taxi or a town car service vs. the DME bus.
