Both can be used. "When it comes to" <-> "regarding".
"when it comes to" is idiomatic.
http://idioms.thefreedictionary.com/when+it+comes+to:
"when it comes to something as for something; speaking about something."
"regarding" is prepositional.
http://www.thefreedictionary.com/regarding
"re·gard·ing . . . prep. In reference to; with respect to; concerning [something]."
Your choice whether you want to sound idiomatic or not.
