One is 15 gal, the other is 8 gal. Which should I use for my HLT, and which should I use for my BK?

I run a 5 gal, AG setup with a rubbermaid 10 gal cooler for a MT. 1.5 teirs (I gravity feed my strike/sparge water and I pump my runnings to my BK).

Any help is appreciated!

Since you are only doing 5 gallon batches I would use the 15 for the boil.

I agree!

The 15 gallon would give you the extra headspace to prevent a boilover!

Yah you'll never need 15 gallons of hit water for a 5 gallon batch. I'm currently using an 8 gallon boil pot for 5 gallon batches and a 5 gallon pot for hot water. As soon as I can afford to step up to 10 gallon batches ill use my 8 gallon brew pot for hot water and a 15 gallon keg for boiling

Use the 15 as the HLT and heat the entire water bill for two back to back five gallon batches.

No need to heat and hold hot water hours before it's used. I'd use the 15 as the BK.
