c# tuning

So after 10+ years of playing a 5 string exclusively I got myself an amazing American Professional Precision Bass, 4 string. And now I’m trying to wrap my head around stringing it. My natural tuning is half-step down, which on a 5 results with: a# d# g# c# f#, which would translate to a 4...

I am looking for a suitable string gauge for a C# G# B E tuning (C# standard) and i am wondering which brand makes longer lasting strings. Daddario or Ernie ball? im only interested in these two brands because they are relatively cheap and easy to find so i'd rather not have any recommendations...
