Honestly, both are okay la, but a few of us mums ended up switching based on what our bodies prefer, some swear by Obimin sebab it's easier on the tummy, but others say Ganilia works better for their iron absorption. I'd say try one for a couple of weeks and see if you kena morning sickness or stomach issues; if yes, switch to the other one and see if it's better. Best thing is to chat with your doc about which fits your pregnancy profile better, especially if you punya existing anemia or digestion issues. At 7 weeks tu memang common to experiment a bit, so don't stress!
