I'm sure that they're all about the same. If you're a smoker stay away from the pills. No Bueno... it's all a craps shoot on how your body likes it... but my vote would be pellets, then IM injection, then patches, then pills, then gels... taking pills all throughout the day doesn't rate high on my list... next to worrying about how much gel I had.. what wiped off etc... less maintenance the better.
