Best tip I can give is that when the nozzle blocks up, don't bother poking at it with the cleaning tool. Take it out and hit it with a Mapp gass torch until it's glowing yellow. Then let it cool and refit. That treatment will burn away all traces of the filament and it will perform like new.
Second best tip, after printing, wait for the nozzle to cool down to below 50C before turning off.
Oh and filament can be very variable, I've had different batches of the exact same filament behave very differently, one of them was just crap and kept blocking the nozzle - don't bother fighting it, just ditch it and get a different filament.
Yes... I know that NOW!!!!!! You could have said 2 weeks ago!

Joking aside, this is the sort of advice I wished I'd got from day one!
