The two yaku [[ittsu]] and [[sanshoku]] are not compatible, because the hand does not have enough [[Mentsu|tile groupings]] to accommodate both yaku.  In turn, this forces players to choose one over the other in the event both are viable during the course of a hand.

When closed or open, both produce the same amount of han: one while open, or two while closed.  Therefore, the value question is somewhat irrelevant.  The balance then stems on the other [[Yaku compatibility|yaku combinations]].  In the case of [[tanyao]], then sanshoku may be favored as ittsu utilizes [[routouhai|terminals]].

According to monthly data in [[Tenhou.net]], sanshoku occurs a little more than double than ittsu.  This is due to the wider number range across the three suits rather than depending on an entire 1-9 sequence of one suit.
