4.8 Vs 5.3 worth 2k more?

I found two 2006 Silverados that are very similar with 4.8(Green truck) and 5.3(Red truck). The 5.3 is in slightly better condition but is 11k out the door compared to the 4.8 being 9k before taxes and fees. What choice would you make for a daily driver with very occasional towing.

5.3 has 157k miles 4.8 has 146k miles

4.8 needs a new front bumper that will run me about $500

I have owned a 5.3 and 6.2 so just unfamiliar with the 4.8

I know I could probably find slightly lower prices but this just seems like the average in my area. I have looked everywhere I can think of with these being my options left over.
