Though FCPx has been controversial since it came out, I’ve fallen in love with it. Coming from FCP 7, I was incredibly frustrated at first, but slowly I have learned the new UI that has allowed me to ultimately see that its really is faster and easier. What once seemed limited, ultimately became faster. Since I don’t share content or need a shared render station, it makes tons of sense for me.
Biggest Pro of FCPx is the crazy fast render times and background rendering.
My advise to you is to get on the FCPx train, its where editing is going.
