OP, your use of the word "squishy" to me, would suggest it might be time to flush your brake fluid. Not just bleed. Apologies if you already know this, but brake fluid is a time based, not mileage based replacement due to the fluid attracting moisture. Under hard braking, the water boils much earlier than brake fluid...steam compresses and your brakes get "squishy". Or, you could have air in the line.
As far as performance, it really comes down to pad surface contact area and coefficient of friction (assuming the brake system is otherwise functioning normally). I imagine all manufacturer's fitment will produce roughly the same contact area so your left with CoF as your variable. The OEM pads' CoF is FF and they were a ceramic compound from the factory. The Akebono ProActs (ACT976 & ACT606) are also rated FF. I was very happy with them for roughly 100K miles as a factory replacement. When it was time to replace them, literally about a month ago, I discovered Akebono had introduced a ProAct Ultra Premium line (ASP976 / ASP606), which is still a ceramic compound for less dusting, but the CoF was uprated to GG. It might just be placebo, but the butt dyno tells me they do stop better than the standard ProAct. So far, the Ultra Premiums don't seem to dust any worse than the standard ProAct. The dust of either is essentially the color of the factory alloys so you don't really notice the dust unless you run a finger through it.
I didn't replace the rotors this time around. Both axles were still in good shape. Still running factory originals on the rear and put Centric Premiums (coated hats, high carbon 4Runner fitment wasn't available back then) on the front along with the ProActs dues to warping of the factory fronts...I blame dealer service bay using impact guns to install wheels.
I do encourage you to spend a few extra bucks and replace all of the brake hardware when you do the pads...retention springs, slide pins, guide boots, etc. And use a good quality brake grease.
FWIW, I also used Centric rotors (high carbon, this time) and Akebono Euros on my BMW E46 convertible. Like the ProAct UP, the Euros are a ceramic blend and GG rated the same as the BMW OE semi-metallic pads. Unlike those factory semi-metallics, my wheels aren't black with brake dust by the time I get to the end of the driveway. I've never regretted the switch.
In short. I think you could spend a lot more money and not get much, if any, better performance than the Centric rotors (or equivalent) and the Akebono UP fitment (currently $46/$43 front/rear @ RockAuto).
Good luck.
