I actually like the Lee collet dies best because they don't microdraw the brass back and they keep internal donuts from forming. I do lap them and final polish with a slurry of JB Bore Compound mixed with Teflon grease and oil. That makes them run very smoothly.

Putting your time, effort, and money where you think it does you the most good is common sense for all endeavors. But we all grow in one way or another, so what needs work can change over time. Hitting a plateau is often a sign you need to shift your focus for a bit, if for no other reason than to recreate your mindset.
