ABS is more difficult to print as PLA. It needs from 235 to 250 C hotend, and 110C bed. It is warping very fast with draft, so less or no part cooling fan, and if possible put printer in enclosure.
Go for PETG if you want stronger prints, you need also higher temperature (240 hotend/70 bed) I tried first Sunlu petg, and afterwards Esun petg. Esun seems better, nicer prints and no stringing.
