2002 Chevy Trailblazer vs. 1999 YUKON, or 2001 Tahoe?

I am looking at getting either a 2002 trailblazer ltz (nice interior and sunroof) with 145,000 miles for about $6,000, i also have found a 1999 GMC YUKON (is very well maintained and the inside is very nice!) with 185,000 for $4,200 and also have looked at a 2001 Chevy Tahoe with a 170,000 miles on it. I do not know which car i want to get can someone help me decide which car is built to last mechanically and which suv performs better than the others. I really do not know which suv i want to get so can someone please help me decide please list pros and cons of each and things i might need to know. they all look decent and nice but i am not sure which one to choose as my first car.
