AT&T HSPA+ enabled area - 4 bars reception.
People make the mistake of assuming that just because they say HSPA+, the network is able to handle the speeds -- doesn't work this way.
I cannot speak for others in their area, but my AT&T area has had the backhaul updated to fully support HSPA + and Verizon has no LTE and there 3G is dramatically slower.
However, you are correct not all HSPA + areas have had the backhaul updated, but in areas that have AT&T is a no brainer.
I average around 8 to 10mb download and 2 to 4mb up. The numbers in your post would be reflective of Verizon here.
