96-99 Vortec 350 or 99-03 5.3?

I just sold my 95 extended cab z71 because I need a 4 door SUV to fit my wife, daughter and dog on our travels this winter. I'm only looking to spend up to what I got for my truck, $3500, and have found tons of 96-99 4 door tahoes with 130-200k miles, and a few 98-03 tahoes with 180-250k miles. My wife likes the ride and fuel economy of my dads 05 Tahoe, but I like the low end grunt, truck ride and looks of the gmt400s. I have had 4 TBI 350s but no vortec 350s, and I know the tbi 350s are solid to 300k miles, what about the vortec 350s? And how many miles is too many for a 5.3? I found 2 vortec 350 tahoes with 130k I'm going to see today for $3300 and $2800, and a couple 5.3s with 180-220k miles, and am torn on what to get. Any thoughts? It'll only see maybe 3000-5000 miles before I sell it in the spring, I only keep trucks about 4-6 months at a time before I sell them for profit and upgrade. The market for the gmt400 tahoes and burbens seems stagnant and very cheap for some reason. I think I can turn a bigger profit on a 5.3 Tahoe or burben, but they also have a higher initial cost. The 95 I just sold I bought for $1200 and sold for $3500, the other 95 I bought for $2500 and sold for $3500.
