I used to be in this camp. However, more often than not, I find that "puching above your weight" is too often the result of op gimmicky builds, metagaming, or exploiting rules issues. In the current campaign I'm in (Way of the Wicked), we are constantly taking on challenges way above our level and making it look easy. It's mostly players with decades of experience who know how to squeeze every advantage out of the rules. I've grown to actually resent that play style.I like a higher band, I just think PF2 is too tight. I am curious what proficiency without level does tot he banding. I might enjoy it more.
Also, enemies were very different in 3E. There where reasons (not always good ones) that something was at X CR. Some of those fights could be tackled by good strategy because of that variety. In PF2 the math is all the same so your hard hitting abilities are sidelined and chances of scoring critical hits vastly reduced. It just simply becomes impossible to face anything in the Extreme+ range.
With PF2, I like the rails. I also quickly finding how the illusion of punching way above your weight can be more exciting than actually doing so through exploits. The versatile stat blocks allow surprises and counter metagaming as well.
