...no disrespect to those opinions, but that's almost a flat out lie.
And no disrespect to your production abilities, but the reason you aren't getting that full production quality sound is because you haven't developed the skills to do it yet, but you will if you simply ask questions on how instead of trying to find the magic software or hardware that will all of the sudden make you sound like your favorite producer. If there really was a "pro production" machine or software then everyone would be using the same thing.
As for MPC's and Tritons...those are kind of dated. MPC's are still useful for their abilities to sample, cut and lay out drums, but it's not going to all of the sudden make you sound "full." Triton sounds have all been overused now. If you take a track composed all of stock triton sounds, you'll find yourself at a disadvantage when you shop your music against someone who is using a newer workstation or creates their own sounds.
Arguably, Timbaland is the number one producer in the world (vs. any genre). He uses neither of those. He has similar weapons, but they are newer and he creates a lot of his sounds.
If you want to hear what I'm talking about when it comes to FL Studio then check my myspace. You'll quickly learn that it's the skills of the producer, not the program.
Whatever sound you put into FL is the same sound that it going to come out. You can take those same beats that you made and remake them in any other program...they are not going to magically sound better. It's all about your ability to mix to get a fuller sound and understanding frequency ranges of instruments.
Like I said if you need help, I'll help you cuz there your music isn't goign to sound better unless you do ask for help instead of switching programs and learning everything all over again with more complicated software.
