you can believe anything in the net if you like. some infos are true (such as ARM is faster than AVR), but some facts are in the details of the FW, thats what gimmick (politics/communism/flat earther/5G protestants/mlm rich quick scheme/scam etc) is all about, covering bad infos with good infos. i follow the dev of marlin FW, if its hitting brick wall, they will drop the look ahead planner, no double extruder, GUI/LCD respond will lag, they will not add bed levelling "re-paralleogram" warped space geometry etc. its like lamborghini can go 500km/h, cheap car can go 150km/h, thats true. but the road speed limit is only 80km/h, thats what not being told. its probably true AVR cant drive full color 1K LCD, but its not the main functionality. the limit hits when you probably choose delta type printer, due to its inverse kinematics heavy trigonometry, but i dont see the point when normal xyz printer can do the same and dont waste much product space/volume as delta is (delta is another gimmickry of pointless innovation imho). but if you can buy lamborghini with full color LCD, at normal car's price, by all mean go for it.
