Isopure vs GNC AMP Wheybolic

I have been using GNC AMP Wheybolic for years and have been pleased with the results. However, my oldest has just started medical school and I need to save a few dollars. Isopure is much cheaper per-serving. So, here is my question:

The two things that I see GNC AMP Wheybolic having that Isopure doesn't is the 15g of BCAAs and 10g of Leucine.

I am 53 years old and am not working out to become big. I would like to be slightly bigger than I am now, but I prefer toned over bulk...if that makes sense. I mention this in case that makes a difference regarding what I need in my whey protein intake.

So, if I go with Isopure, do I need a source of these BCAAs and Leicine? If so, is it best to stick with GMC?

Just looking for thoughts and opinions...thanks!
