Got into the series last week and a couple of questions going from DMC4 to DMC5

So I beat DMC1 and DMC3 already (skipped 2 because I heard it was bad). I think I 'm halfway through DMC4 right now? I'm on mission 10 I think. Unfortunately it looks like there's no way to play the whole game completely as neither Nero or Dante on NG+? Kinda a bummer as I'm getting more of a hang on the exceed ability a bit more. Anyways my main questions are:

* Should I go straight to DMC5 after DMC4? Or is it worth trying out all the different characters as there are quite a lot of them. DMC3 I did maybe 5 missions as Vergil and then moved on. * So it looks like there's no Turbo Mode for DMC5 on PC, but it's available through SSSiyan's mod which I heard is a pain to get working. Does the Turbo Mode also effect the in game timer / cut scenes? Trying to see if it's worth the effort to get the mod running.

Thank you! Loving the series so far.
