Creality CR-1012'x 12'x 15" (300mmx 300mmx 400mm)... i was thinking of getting another one
For a printer that is only 300x300 I'd get an IDEX printer like the Hictop D3 Hero. Dual head means dual material, mirror mode or duplicate mode. There's a lot of added features with that. (I have four)
Otherwise, go big. 300 is a mid-size printer. Its not as small as an Ender3pro, but it sure ain't no CR10s-5 at 500mm^3.
At the 300mm range you still have to break up even a helmet. Frell that! I put a helmet on to print on Monday and take it off the printer on Friday in one piece. No seaming!
At 500mm cubic I run entire chest pieces or tall leg pieces in one go and I'm not a small guy at 5'10, 210 pounds.
