Upgrade from C1 LE to Pro?

I am a part time wedding photographer with a slowly but surely increasing workload. I'm using C1 LE but am wondering if the Pro would suit me better now. I've looked at the feature comparison but am wondering if any Pro users who have previously used LE could give me their opinion regarding the difference, please? At the end of the day, its the final print that matters most - is there an improvement in that with Pro, do you think?
I'd really appreciate your opinions,
Many Thanks
Trudy
