I have the Seeker 2 (not the Pro version), and I've been able to compare it to the Seeker 2 Pro, because I hang out with people who collect flashlights. Based on that comparison and the video that Olight has up with the S2R II, I'd say go with the S2R II... the Seeker 2 has more light output (3000lm tops as compared to 1150lm) and more throw, but the S2R II has plenty of output and throw, and it's "floody enough" for what I think you want. Also, it's got a cheaper MSRP ($69.95) than the Seeker 2 Pro ($139.95).
Keep in mind that both of these lights have the magnetic connection charger, and use customized (read "proprietary") cells. If it bothers you that you won't be able to swap out the battery for a stock 18650, neither of these lights is one for you. I haven't had a problem with my Seeker 2, but then, I haven't been in a situation where I've used up the battery and had nothing else to shed light while I waited for it to charge, either.
