I mainly use Esun & Sunlu PLA+, they both work great and can go up to 35mm³/s reliably.
From your pictures, you seems to have a lot of warping, you should probably disable auxiliary fan for this print.
About those blobs, that’s very strange, make sure to set “seams” as aligned (but that’s not the problem here) and set a correct PA value (dont use printer autocalibration, set it manually either using Orca slicer or Gcode in bambustudio on filament start gcode), something near 0.02 should work, not the best but you should be good enought.
