LR6 didn't have any significant new features over LR5.7 that interested me. I think it comes down to whether there is equipment supported in LR6 but not in LR5.7 which you may be considering purchasing. In my case, I have been thinking about upgrading my Canon EOS M mirrorless body to the EOS M5, as the price on refurbished units has been dropping lately. I do not think that body is supported in LR5.7, so I am considering picking up the upgrade to LR6 while Adobe still offers it for $80. I am satisfied with my two dSLR bodies -- Canon 5D Mark 3 full frame and Canon 7D Mark 2 crop -- and have no plans to upgrade either for the foreseeable future. So a LR6 upgrade would probably get me by for at least a couple of years and give the competition more time to develop their Lightroom alternatives. Another part of me doesn't want to give Adobe any more money and just move on. However, I need time to figure out what I would move on to, and I'm concerned that Adobe will pull the plug on the LR6 upgrade option soon as another strong arm tactic to get people to move to their subscription model.
