If you're into 3D fighters in general, definitely give Tekken 7 a chance. If you're experienced with DOA5LR and good at it, you'll transition into Tekken 7 ok, though you'll need to learn the differences in the intricacies of the systems. In DOA you tend to develop your 3D meta game, which I find helps out in learning Tekken (though proper movement & utilization of tools feels more emphasized in T7).
Also most DOA players from what I observed dont like/hate on tekken for silly strange reasons, in which case I feel they shouldn't play if the game is not for them and if all they'll do is complain and call it "braindead" when Tekken is just as deep
