Canon G series or Epson L series printer?

Hello im a college student planning to buy a new printer because my ancient printer just died. The technician said that it cannot be saved anymore because its too old and the parts are not available now in the market. I asked him if what brand he recommend and he asked me if where would I use it. I replied, only for document printing and scanning but i only do that once a week and every examination. He said that i should not buy epson printer because i need to use the printer more often so that the print head will not be clogged and replacing that part is expensive than in canon printer heads. What other issues that epson and canon have?  Im planning to buy Canon G3010/G2730  or Epson L3210/L3250. Thank you in advance!
