Whichever one you decide it's best to learn one and keep practicing until you have totally got to grips with it. It can be confusing looking at both at the same time, as they are completely different ways of working. I mastered gel first and loved it but once I mastered L&P I was hooked and yes, the clients do prefer L&P near me.
My personal preference is acrylic hun but I still do gel as well.
Good luck with whatever you decide x
