its all about what works best for you
if cubase works great and no problems plus it gets the job you need done, then i wouldn't be switching
on the other side if you are a user with more need than just the basics, then logic is the best for you
logic requires more than being a good musician, there is soo many features in logic that even the pro musicians don't know it existed
it took about 6 months learning cubase inside out, 3 months on fruityloops, 6 months on protools, and 2 months with Garageband 🙂
yet there is alot i don't even know about logic 4 or 5 or even 6
I'm on logic 7, and i feel like I'm half way with 7, but i can do incredibly crazy things that I'll never imaging doing with cubase, fruityloops, BG, and protools
first few months on logic is horrible and i can say that every user here will agree with me, but after a while you get surprises all the time ( good ones too )
you start to work fast with bunch of key commands as you go along, building autoload also makes logic even easier to use
this is my point of view and so as other logic users,
but other users will say that all they want to do is record audio and add a few midi instruments along side, them people don't really need to switch to logic
protools and cubase is far better than logic when it comes to that
so the question is what do you do and what do you want out of the two app that both don't have compare to each other
in terms of logic working better than cubase on mac is a lie, every user knows their trick for making things work
some people works better with logic 5 on windows but perform crap on mac
others perform better on mac using cubase than logic, it depends on
1: the system ( G5 dual 1.8 - 2.7 and rams 2 - 4 gb)
2: the user ( what the user is planing to do )
3: knowledge ( building good skills on one application is better than buying mac worth of $5,000 and switching applications to find the best one )
using logic express is like using garageband except with logic gui ( if you get a bit use to express and you start to love it, then upgrade to pro, this forum will be able to help you get you on your running shoes
but if you feel like express is slowing you down and too complicated then don't waste money going to pro and take some more time with cubase, you might perform better than someone using logic pro
