Bankai Ichigo or kenpachi?

So I don't have either of those characters so I need a slash DPS one that can be used now and with zangetsu later. It's likely that kenpachi will rerun alongside zangetsu and I was wondering if I should grab bichigo and save jades or pull for kenpachi when he reruns and get Toshiro for now. I know that there's a noticeable difference between bichigo and kenpachi but I am more concerned about Ichigo become desolate since its possible kenpachi might get buffed and might be better tuned with zangetsu and bichigo might not be a good choice and we don't know any of that yet. What do you guys suggest?

Yes I don't have Toshiro either but I wouldn't pull for him even if he reran. I don't particularly prefer kenpachi over bichigo or otherwise either. I want to get the free bichigo and avoid kenpachi (if he reruns) if that's okay.
