Aiyoh, both ada pros and cons, depends on lifestyle you lah! Implanon bertahan 3 tahun so less worry about refill, tapi some of my mum friends dapat spotting at first. Depo inject every 3 months so kena rajin pergi klinik, but balik normal faster kalau nak pregnant lagitau. Best you discuss with your doctor or nurse at clinic dekat rumah, they can assess based on your health and apa yang suit you best, don't rush this one sebab kena comfortable 9 months or more next!
