Logic is quite a steep learning curve and only runs on a Mac and was designed mainly for people who can't play. It allows them to bugger about all day and pretend the can play.
I found logic ridiculously easy to work out how to use, and I play several instruments which I record. I use midi connected to my keyboard to play VSTis.
With all DAWs, which one is right for you is not about how good the program is, it's really about how your mind works. All of them do a good job for the interested amateur, and some excel in some aspect over another.
Reaper is a great program with very low cost. I'm going to be very tempted when the next version of Logic comes out, because I get the feeling they're not going to do an upgrade price.
If you've got Cubase and a PC, then I'd stick at it. While I sometimes find cubase cumbersome, it is a very full featured program, and there are loads of online tutorials. I'd give them a try before you consider a move, and if you do consider moving try reaper first before going any further.
