Crabbing into the flare may work for little aeroplanes in light Xwinds but have watched it go wrong too often. There is no doubt in my mind that slip in the last couple of hundred feet leads to a more consistent and polished outcome.
For you...
. I've flown crabbed approaches for the last 30 years in xwinds that have been very naughty at times and never had any problems at all. I sit in awe at the judgment required to do a slip approach, to me a crab approach is a no brainer, I do them without any conscious thought.
There's no right or wrong way, just the way that you prefer. The end outcome needs to be a safe landing, if you are making safe xwind landings consistently then everyone is a winner.
