Ender 3 S1 Pro w/ klipper keep clogging

Hey! So point is in the title but I'm wondering if it's just garbage PLA filaments or some other issue. Like I've tried two different black filaments from Amazon which both melted like rubber when I just extruded them in the air. Blobbing into a thick teardrop if that makes sense. I went up to 240°C with one out of annoyance but it clogged completely mid print. I also generally use 195-200°C regardless of what is the factory recommended temp because that seems to be the best result for over a dozen filaments so far; very little stringing, good layer adhesion and my thermistor is a few degrees higher than room temp (after like a day of no use).

So I wrote those black filaments off (and it somewhat makes sense, those have the most amount of coloring) but now using some 3DJAKE Metallic Emerald (what's the consensus on 3DJAKE filaments?) and another Azure or PM filament I forgot the name of I still get clogging sometimes. Each time I took apart the heating block I replaced the nozzle (tried different types). I also really hate disassembling the whole thing. Like why we still don't have color coded screw heads for stuff that's expected to be DIY repaired and maintained, but I digress.

The only mod I use is a blower style fan with a 3-way duct that works wonders. But I also like to use very slow (15-20m/s) speeds for first layer and outer perimeters, otherwise I'm doing 40mm/s for other perimeters and 70mm/s for infill. So far that worked very well but I mostly print decors with high quality required.

Also, the black filaments were stuck even inside the teflon tube, but the other filaments only stuck (but real well) inside the "neck" above the nozzle so those were easier to clean.

So what I should be doing differently?
