Lower kvs mean more torque, but once you gear up to match the speed of the higher kv motor, you lose torque at the wheels (thats what counts) and you increase the current. So why would you NEED a 1521 in the first place? So you can run higher voltage without reducing the current for more power. e.g you can run a 1521 1.5D on 6s which is too much for the equivalent 1515 1.5D.

I have seen 75A spikes and average of 15A. The bigger motor will produce more torque then the smaller one and will require less AMPs to get moving. I also have found that my Mega that's in my MBX5T consumes less AMPs then a same size and Kv Aveox motor. That's due to the Mega being a 6 pole motor and producing more torque then the Aveox. Before I though it didn't make sense either, but once I saw it for myself, I can definitely say the larger motor will not strain so much to get a heavy truck moving. It's a good experiment to try
.
Edit: Maybe I found the right set up for my BPP truck. I'm not speaking for anyone else, so the best motor that fits the bill will do, but for $20 more, why not try the 1521/1Y.
