The BEST pill is the one that works for you. I know, doesn't help much. But the thing is, we all react differently to hormones and to different levels of hormones. A person can luck out with one, but it often takes 3-6 months of trial and error to find one that has acceptable side effects.
Your doc will have the best idea, since she/he will have the PDR file on what types and dosing levels your implanon had and find the "matching" oral pill.
Honestly, though, if your glorious hubby is getting fixed you might just want to stick with icky thwibbt condoms + spermacide for the time being. In large part because it usually takes several weeks for the pill to become effective (I honestly don't know if there will be a lag time with your implanon being removed if the oral pills have a lag time, so it's a thing to ask your doc). It's also impetus not to push off the vasectomy forever. Of course, if you plan on staying on the pill (some women get benefit from the hormones, some don't) it's worth the time investment to find the right one.
