I was raised by parents who had a very strict Catholic back ground themselves, but who were greatly infulenced by the flower children of the 60s and 70s. So, my up bringing in the Church wasn't so great.
I ended up being a lasped Catholic by the time I hit my 20s. I along with my dh and our girls returned to our Catholic faith 4 years ago this Jan 1st. Before we returned, I did look into other churches lightly. I kept coming back to the fact that Jesus called Peter the rock on which he would build his Church. The Church he built is the Catholic Church.
There are many other differences such as with the Pope, the Eucharist, and Church authority.
